semmtex Posted July 17, 2015 Share Posted July 17, 2015 First I had a corrupt btrfs docker image. I recreated this and re-added my docker containers. So far so good. However every time my server crashes. The problem lies with the Plex docker. Whenever the Plex docker crashes I can still access the Unraid Webui, however stopping the plex docker results in an unresponsive Webui, and a according to the docker ps command still running Plex docker. Normally I proceed by killing the docker daemon (rc.docker) which reinstates the Webui, although not this time. Only solution became a hard reset. Any help or indication on how to prevent/fix the problem is much appreciated.

trurl Posted July 17, 2015 Share Posted July 17, 2015 Boot in SAFE mode. Go to Tools - Diagnostics and post result. I am moving this to General Support since it is not really a Defect Report. Quote Link to comment
semmtex Posted July 17, 2015 Author Share Posted July 17, 2015 Sorry 'bout that...thanks for the move. Quote Link to comment
semmtex Posted July 19, 2015 Author Share Posted July 19, 2015 Booted into SAFE mode, attached the diagnostics zip-file. phoenix-diagnostics-20150719-1417.zip Quote Link to comment
trurl Posted July 19, 2015 Share Posted July 19, 2015 Does it happen in SAFE mode? Quote Link to comment
semmtex Posted July 22, 2015 Author Share Posted July 22, 2015 Been running okay so far. Really think it could be a plugin or installed package? Quote Link to comment
semmtex Posted July 23, 2015 Author Share Posted July 23, 2015 Spoke too soon. Here's another crash. Had to connect monitor, since it totally unresponsive. Quote Link to comment
semmtex Posted July 23, 2015 Author Share Posted July 23, 2015 Did that a week ago, let it run for more than 25 hours. Didn't find anything. I reckon it's probably old or faulty hardware, but no clue what it might be myself. Quote Link to comment
aptalca Posted July 23, 2015 Share Posted July 23, 2015 Oh the jiffies. I was having that cpu stall issue a few months back. It happened 5 or 6 times over a 2 week period. It was annoying because the server would hard crash. I suspected it was Plex related, but wasn't sure. At the time I was on beta 5a, wasn't using docker, Plex was running in a xen ubuntu vm. I then updated to a more recent beta, moved Plex to docker and haven't had the issue since then. Here's my thread from back then: http://lime-technology.com/forum/index.php?topic=38119.0 Are you using xen by the way? And are you on the latest plexpass version? Because a bunch of people had that issue back then but i haven't seen any reports recently. I thought the underlying problem was somehow fixed either by an update to kernel, or software or by people stopping using xen, etc. Quote Link to comment
semmtex Posted July 23, 2015 Author Share Posted July 23, 2015 I'm not using Xen, and running the latest unraid version with a couple of dockers (Transmission, Plex, Sickrage, CP). I'll take a look at the thread, maybe there's something in there. Quote Link to comment
semmtex Posted July 28, 2015 Author Share Posted July 28, 2015 Still having trouble, this time it crashed just by adding a torrent into transmission webui. It started okay, but after about 5 min. This happens...(see picture) Help much appreciated! Quote Link to comment

semmtex Posted July 30, 2015 Author Share Posted July 30, 2015 See Check Disk Filesystems in my sig. Was just reading another post about kernel panics in which you suggested the same. It's def on my agenda for this weekend! Thanks. I'll report back later... Quote Link to comment
