Three times in the last 4 weeks my in-house FreePBX server has shutdown on it’s own. I’m trying to find the cause but not having any luck. The command last -x | grep shutdown | less didn’t show me anything. I checked my UPS log /var/log/apcupsd.events, it didn’t show anything either. Is there a log I can check to see what’s happening? I want to see if something is sending a shutdown command or if this is some kind of system failure.
I checked that log first but it didn’t show anything. I received the “offline” notice at 11:29am and turned it back on at 11:40am. The log doesn’t show anything until it’s turned back on.
