Windows service randomly stops with no indication why

2024-03-08 Thread Jay Madren
Running PostgreSQL 15.6 on Windows Server 2022. The database service
randomly just stops and the Windows Service auto-restart options don't kick
in. The stop is unexpected (not a controlled shut down) because after
restarting the service the postgresql log states that the database system
was interrupted, not properly shut down, and automatic recovery in
progress. There's nothing to indicate exactly when it went down, other than
the timestamp of the last log entry before restarting it.

There's also nothing I could find in the Windows Event Logs other than when
the service is started each time.

This is occurring at random times, day or night, around 0 to 2 times each
day.

Any clue as to what's happening or how to investigate this further?

Thanks,
Jay

It is not set (commented out). I assume the default is "warning". I will
set it to "info" and see if that reveals anything.

restart.

I had already changed the recovery options to restart on first and second,
then run a command script that starts it on the third count. None of them
appear to work, which means the shutdown appears to be "normal" to Windows.
Or maybe postgres doesn't set exit levels for Windows to act on.

This is what I suspect also. This server was recently "taken over" by a
third-party management firm that corporate dictated, and they have loaded
all kinds of monitoring and security crap on it. I have reached out to them
but not gotten a response. I will push harder on this.
