Can't stop jail or reboot FreeNas because process in a Jail won't stop

It seems I can't stop the jail or reboot FreeNas because a process in a Jail won't stop

root@freenas:~ # iocage stop radarr_1

I tried to kill the process with "kill -9 18378" but it doesn't kill it.

Can someone help me?

Tried to destroy the jail and now iocage freezes, and now I can't see the jails anymore in the web interface. The only option I see is to do a hardware reset or shutdown and that is not something I want to do.

This is 11.2 by the way.

Were you able to resolve this?

 

[Neon]

I resolved it by doing a forced shutdown of FreeNAS by holding down the power button, not the way i wanted it to do.

I had the same issue as well and also had do a hard reboot.

Same here. Not quite sure how to repro or report this bug, it's quite intermittent. Interestingly, my issue was with radarr as well so maybe it's something to do with mono...

I have this same issue after updating to 11.2-U1 and it is also intermittent and with sonarr for me. When I force stop the jail my SSH session disconnects but iocage still reports the jail as up. For me this is a 11.1-U4 jail that I have not upgraded to 11.2 yet and had created it from command line in iocage 11.1.

I am unable to even initiate a reboot from the GUI, I select it but no restart. On the console I can select reboot but the reboot fails while shutting down there it pauses on "Unmounting user-supplied file-systems" for a while, then multiple errors with rc.shutdown terminated abnormally and then finally init: some process would not die ps axl recommended. At this point hard reset.

My jail with sonarr is definitely the problem as all other jails, vms and functions appear to work correctly when that jail is "hung" Going to check my zpool status, etc but so far no clue either.
