My Hetzner server has been crashing intermittently for the last two or three months and I can't trace the reason for it. After every crash I check
/var/log/syslog and apache2 logs, nothing. Just gaps in the time when it was down. Luckily, Hetzner has a great automatic server reset function which works quite well, so the server is up and running within 5 mins of doing the reset.
The most recent crash was in the early hours this morning. I rebuilt couchpotato last night which caused the server to be flooded with a ton of movie downloads from the backlog it had. IThis meant that rutorrent super busy DL'ing movies, CP renaming heavily and ACD_CLI was working extra hard to get them uploaded. Right before I finished up with the server, I checked the load and everything was running smoothly except the hard drives were taking some strain.
What can I do to diagnose the crashes? It could be anything, hard drives might be going or some app might be causing the crash. What do you guys think?
These are my stats:
OS: Ubuntu 16.04
QuickBox Version: 2.48
