bauerknight Posted August 3, 2015 Share Posted August 3, 2015 Hi, I am having stability issues with my Unraid 6. Unraid 5 has been running rock solid but lately I cannot get my unraid 6 stable. By stable i mean i cannot hit the unraid web gui or any of the dockers webgui. Only thing i can do is telnet into the box but a 'reboot' command doesn't even reboot the server. I have a feeling it could be the plex docker but I've tried using the plex plugin and it still crashes. I've tried everything from using another usb flash drive to deleting the dockers and starting over each time. From what i've been able to look at the syslog it's some sort of kernel error. Here is a snippet of my syslog right before it crashes. If you need a complete syslog i would have to wait to get home to manually reboot the server.

trurl Posted August 3, 2015 Share Posted August 3, 2015 You posted this in v5 support so I am moving this to v6 support for you. Have you tried memtest? Instead of a snippet of syslog, go to Tools - Diagnostics. Quote Link to comment

Instead of a snippet of syslog, go to Tools - Diagnostics. Hi, yes i've done a memtest and it passed. I can grab the diagnostic once I force a reboot and get the web gui running again. Thank you.

dgaschk Posted August 3, 2015 Share Posted August 3, 2015 Do not reboot. Enter "diagnostics" on the command line. A file will be created on the flash. Quote Link to comment

RobJ Posted August 7, 2015 Share Posted August 7, 2015 I'm sorry, but I don't have answers. In your last syslog, it ran for several days before crashing, and you ARE using the system to the max! But there aren't obvious clues as to why or where it's failing. I suspect if you ran without Plex for awhile, you would not see any crashes, but that is obviously undesirable. I WILL point out one item that seems unusual, and makes me wonder if it's totally supported, by every module that handles it. That's the foreign characters (possibly Unicode?) in certain folder names. Here's one example (same path seems to be displayed 2 ways) - Aug 6 04:30:01 MediaTower logger: >f+++++++++ htpc/TV PreTeens/Gamer\#342\#200\#231s Guide to Pretty Much Everything/Season 01/Gamer\#342\#200\#231s Guide to Pretty Much Everything - S01E02 - The Gaming Club SDTV.mp4 Aug 6 04:30:03 MediaTower logger: ./htpc/TV PreTeens/Gamer’s Guide to Pretty Much Everything/Season 01 Here's another example - Aug 6 03:26:46 MediaTower logger: ./htpc/Output/[www.dydao.com]周星驰 高清åˆé›†/[www.dydao.com]ã€å‘¨æ˜Ÿé©° ç®—æ»è‰ã€‘Lawyer.Lawyer.1997.720p.HDTV.x264-XXFANS/Lawyer.Lawyer.1997.720p.HDTV.x264-XXFANS.en.srt Aug 6 03:26:46 MediaTower logger: cd+++++++++ htpc/Output/[www.dydao.com]\#345\#221\#250\#346\#230\#237\#351\#251\#260 \#351\#253\#230\#346\#270\#205\#345\#220\#210\#351\#233\#206/ It would not be surprising at all to see a file system choke on those! At the same time, I cannot say they have any connection AT ALL to the kernel crashes. Quote Link to comment
bauerknight Posted August 7, 2015 Author Share Posted August 7, 2015 Thank you for looking into it. I guess worst case is that I can downgrade to unraid 5 and see how that goes. I will miss all the awesome dockers though. Quote Link to comment
