JR is headed to Houston with a group of his partners. They bought a bunch of boats and are headed there now to see what they can do. I told him to get a Tetanus shot and keep an eye out for the over 1M alligators that are displaced and probably not in a real good mood, not to mention the snakes.
And the floating islands of fire ants!
JR is part of famed Cajun Navy now....lot's of good people doing good work for strangers.
Sometimes you see things that give you hope for humanity!

My 5K iMac is annoying me. It has done this for a long time but it feels like its getting worse. I constantly come back to it and it has "restarted due to a problem". I'll be working away and the screen will flicker to black then the chinese message comes up and it shuts down. An old fashioned kernel panic I guess, but what is causing it? I need to disconnect everything and see if it does it. Frustrating!
Any luck with this? Been racking my brains - but the truth is it could be a zillion things. With such an integrated design specialist knowledge is often required. Oh, and that special Apple rubber mallet.
Thanks Nick! Nope, doing triage as we speak. You are right about the zillion things. What I have done is bring a 27" iMac out of dry dock to facilitate backing up to the 50TB Drobo 5D I just received . Trying to use the 5K for this is hopeless because it restarts all the time. So, I'm recreating the failed Drobo on the new one and I have disconnected everything from the 5K iMac, except for my 16 bay NAS. I figure that I can determine if it doesn't like one or more of the external RAID arrays this way. If it doesn't kernel panic and restart in the next 24 hours I'll at least have that answer. Apple suggested that I do an OS X clean install and then add each bit of software, one at a time and run it to see what software it has a conflict with. Um, I would rather lay it in the driveway and make a couple of passes over it with the Landcruiser than spent the rest of my natural days performing that diagnostic.
Frustrating because this is my newest 5K so I'm not thrilled about taking it out of service. I'll be ordering on elf the iMac Pro models late this year when they become available, but I'd still like to have this one running somewhere. So far i have moved some files around and worked on some stuff and it hasn't restarted, so maybe it is an array that it doesn't like. I'll reconnect the Drobo units in 24 hours and see how it behaves for a day, then attach the OWC 40TB arrays one by one and monitor those until something triggers a restart. If it ends up being software, I am not going to go through that, I can go shoot for a day and make the cost of a new loaded iMac instead of spend weeks of my time on this one.
Jim, you may want to pick up a copy of Techtool Pro. It runs a ton of hardware diagnostic tests on pretty much everything in your iMac to tell you if it's a hardware problem. I find it much more comprehensive than the built in Apple diagnostics tests.
Today is just one of those days. My QNAP 16 Bay array sent me an email a month ago telling me that they found a hiccup in their firmware that might corrupt data. The message had instructions on how to initiate a "scrubbing" protocol, which took over a week. When the scrubbing was complete I ended up with files moved around and new folders created with number and letter designations. Somehow the scrubbing protocol found files that had been corrupted and created folders to put them in. So, I have a dozen folder that I have no idea where the images go and some of them are corrupt as well, or they don't exist at all. I just spent an hour with QNAP tech support (excellent folks, really!)and we figured it out. Now the 16 bays are running another protocol which may fix those misplaced files and restore them to their proper location, if that doesn't work, I'll be reformatting and reloading everything.
I did find something interesting out though and I'm going to begin replacing the 6TB drives in the 16 bays with 10's. They showed me how to do that in the control panel and they can be hot swapped. I'd much rather do that at the rate of a couple of drives a month rather than fork out $500 x 16 at once.

Jim, I have no knowledge of your storage topography - nor should I. I just want you to know that "reformat and reload" had the alarm bells going off over here. I just want you to take a day out on this, and sit down with pen & paper and satisfy yourself that there is no chance of a cascade failure or of simply loading bad data.
I appreciate your concern, I've been pretty stressed over it today as well. My back ups upon back ups will cover me, but I blew 12 hours today on something I had no intention of doing and that frustrates me.
Here's the set up, I have two 8 bay QNAP NAS arrays set up as RAID 6. I typically don't work from those files, just send a modified folder to it when I've retouched them on another/faster array. Additionally I have four 48 TB RAID 5 arrays on the shelf below it that are all Thunderbolt 2 interface. Those mimic the files on the NAS. My HQ work station has four 50TB Drobo 5D units configured in RAID 5 with the same files on them. Last, but not least, I have four tubs of internal drives with back ups of everything, in anti-static bags and anti-static cases in climate controlled storage at a third location.
I think I'm covered unless Kim Jong Bad Haircut blows something up overhead and fries everything., in which case there'll be more to think about than my archives I guess.
So, this afternoon I took a deep breath, walked away from everything for an hour or so and laid out a plan to get everything back to where it was before this all unfolded. The QNAP NAS has about a dozen client folders that have been renamed in the scrubbing. Based on the hour I spent with QNAP Tech Help today I am deciding that those folders are not reliable. Next step is to verify that the other zillion folders are intact, double check them against my redundant arrays, then I'm going to reformat the NAS and recreate it using 10TB drives. I'm longing for slide pages at this stage........well not really
And you are correct, the reformatting regimen that QNAP had me do today did absolutely nothing to repair the files corrupted by their firmware hiccup. The one ray of sunshine in all of this is, with two 50TB Drobo 5D's and a 48TB OWC array attached, the 5k iMac has not gone toes up in 8 hours. We'll see what it does overnight. I threw a lot of files at it a while ago so it'll be working all night.......or not. Weebeesee.

Funny you should say that: mine does the same thing. Often it's while Lightroom is doing a batch of DNG conversions at the same time as 1:1 preview renders, but not always.
Mine's a "late 2015" maxed out on RAM. There's no rhyme nor reason to the kernel panics. I've seen it happen when nothing is going on but checking email, no background tasks at all. I unplugged everything yesterday and let it run for five or six hours and it was fine, then I plugged in two 50TB Drobo and began moving files. Didn't have any problem for about 8 hours of continuous file back up, then it shut down and re-started. I'm completely baffled and there's no way I'm doing that one by one software thing that Apple suggested. Guess I'll have to live with it. The model right before it that I have at HQ will transfer files for a week straight without a hiccup.
Glad to hear that you got yourself away from the problems and had a session with pen and paper - just the ticket!
Suggestions / Questions (to provoke thoughts):-
1) Do not transfer anything to or from the installation at HQ until at least a week after your home setup is back working and deemed stable.
2) Did any of the files that went bad on the QNAP come from the failed Drobo? If yes then quarantine both. Rebuild the QNAP and only load data from other than the failed Drobo.
3) I assume that the QNAP has data loaded / read via Ethernet wired network? If not make it so.
4) You mention that the Drobos are on a shelf under the QNAPs, and that the Drobos are on Thunderbolt 2. What is on the other end of the TB 2 cable? The QNAPS ? The iMAC ?
5) Remember that the Thunderbolt interface effectively extends the host computers system bus to outside the computer and along to the TB device. That means that device option ROMS and / or glitches can insert themselves into the host memory space via DMA. This can often result in the spontaneous re-boots that you have at the moment. I have a strong prejudice in favour of wired Ethernet as an alternative.
6) Another cause of spontaneous re-boots is something getting too hot, or thinking it's too hot.
Hey guys, great to see the chatter about DCS. I've invested a lot time into it over the last few years (as well as quite a few ££££). Don't seem to be progressing skill wise though!
Have to back up the comments re using decent stick etc, I am using a Thrustmaster Warthog but added an extension tube to it last year and it made a massive difference along with using a WheelStandPro.
I did also try the Oculus Rift, which gave one of the most lifelike experiences on a PC I have ever had, but unfortunately it also gave me severe motion sickness, so I returned it.
That's pretty cool, but I'm not sure the FAA would approve of parts of that display. I love how obvious it is when you get too far into the buffet that the rate of turn drops dramatically. An A-10 pilot I know described it as "elephants walking on the wings" when the buffeting got critical.
Well Harvey just hit the rest of Texas, the state is running out of gas very rapidly. This will be interesting, from what I can see there are very few gas stations with any fuel in the metroplex. Better buy a Tesla tomorrow Seriously though, the rumor is that 12 refineries are shut down along the Texas coast and that this will seep northward quickly. Imagine the ramifications if this lasted for even a week, trucks, the airlines, the military has a gazillion gallons of JP4 tucked away somewhere, but the rest of the country doesn't. What a whack to the economy.

Wow that is impressive I bought a Saitek S52 stick and throttle about 18 months ago, but have been completely unable to make them work under Windows 10 When I try to load the latest Drivers from Saitek Windows 10 refuses to load them, sating they haven't been verified!!! On the few occasions I felt strongly enough about it to phone Saitek I just end up in a queue and give up!!!
