This is the second time this has happened to me on two different VPS. Logs says insufficient memory but I have 2GB and 250MB swap for small websites. And its crashing on off peak hours.
this is my journalctl data at the time of the crash.
I cant get mysql to restart. my db files appears intact. Problem is restarting sql. I have tried to rename those 3 ibdata files and then rebooting sql. that worked once before but not this time.
