Running PVE 7.2-7. An Ubuntu Server VM keeps turning off by itself. Node and VM have been running O.K. for a few hundred days. No update to PVE or the VM could've caused this, as I haven't updated any of then. Where can I find any shutdown logs as to what initiated the shutdown? One indication of the cause could be whenever I try to query a table (around 2M rows) of the PostgreSQL running on the VM, it sometimes causes the VM to randomly shutdown as I mentioned. Last time it shutted down was a few hours ago, and I wasn't doing anything particularly suspicious on the VM.
