Hi all I’ve been having a issue with my TrueNas, various jails have been crashing, with some tracking down it was discovered that the root problem is coming from the Plex server/process/jail miss behaving, causing the NAS to kill processes, eventually killing the Plex server also. Server Version#: Version 4.76.1 Player Version#: NAS Version#: TrueNAS Core TrueNAS-12.0-U8.1 - but this problem has excisted in previous TrueNAS versions also. need some help trying to figure out why.

I am running TrueNAS Core 12.0-U8.1 and have only had intermittent (every 2-3 months) dumps where it exited on signal 11. I do notice that it looks like you are trying to use IPv6. I don’t think that is the issue but I would disable it just because on both TrueNAS and Plex. This link might give you some help. I’m not sure it is exactly related to your issue but it sounds close. > **[Swap usage is killing my Plex jail - after running for years until now](https://www.truenas.com/community/threads/swap-usage-is-killing-my-plex-jail-after-running-for-years-until-now.98289/)** > > Version: TrueNAS-12.0-U7 > CPU: Intel(R) Core(TM) i3-4170 CPU @ 3.70GHz > Memory: 16GB ECC > Storage: 1 volume with 1 vdev of 6 X 3TB drives in RaidZ2 > > I have a really weird issue that just started happening in the past couple of weeks.

> [@phoneguyinpgh](#): > > I do notice that it looks like you are trying to use IPv6. how where you seeing this, as I def don’t have it configured. thanks for the link, will go have a look. anyone else that can help, that might know how to dig deeper, this is a pretty pesci serious problem that I want to get resolved. Can’t keep hoping it gets fixed in a next version… G ---

Do you believe Plex is the issue, or is another process using all of your memory? It’s worth checking the memory usage on the system periodically to see if one process has run away. Leave `htop` running, sorted by **M\_VIRT** , and check it periodically. I see qbittorrent mentioned, which makes me wonder which version of libtorrent-rasterbar is installed. Version 1.x is OK; version 2.x handles memory _differently_. Do the crashes occur overnight, when Plex might be running scheduled tasks? Sometimes a corrupt media file can cause problems when it is analyzed, for instance. Try disabling extensive media analysis or audio track loudness analysis as a test. `Settings` → `Library` → `Analyze audio tracks for loudness`: never `Settings` → `Scheduled Tasks`: Disable everything as a temporary test Try sharing [server logs](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) after the problem occurs. ---

The trueNAS guys with whom I shared my TrueNAS logs pointed at Plex causing a problem, to first handle it TrueNas kills the qbittorrent jail, and when that does not stop the problem it ends killing the plex jail. this happens mostly/always 01:00-05:00 daily so probably as you hinted one of these automated batch processes. how do I check the libtorrent-rasterbar version. thanks, will change these settings and see.
