I have PBS running as a VM on PVE 6.2-11. Sometimes it runs for something like over 20 days, and then it all of a sudden locks up and the external USB drive pass through starts showing. I did some reboot and sometimes the PBS comes back but keeps showing errors. Only when I finally issue a kill -9 or kill 15 and the PBS starts again things are running as normal. However the syslog gets erased. Is there somewhere I can find out what happened?
