Server Failure

Post by smied »

24 hours = 3 failures
Server stops responding (ping works)
Login to the server fails, as well as to sites connected to keyhelp.
After some time, when trying to enter the server, an error is issued:
MySQL - Connection Error: 2002 (Connection refused)

Only restarting via ssh helps

Server: 2 cores 1 ram
(2 sites Attendance 5.000 users per day)

Sounds like an OOM kill.
Relevant logfile entries?

grep "Killed process" /var/log/syslog

Killed process 614 (mysqld)


https://www.keyhelp.de/en/

The site says this:
Please note the following installation requirements:
Operating system: Ubuntu LTS or Debian
Memory: At least 1 GB RAM

So how much then do you need?

That's the absolutely minimum you should have for the system to work.

I think, you need at least 2GB RAM or more.
