What am I looking for?

Found what it was, did a repair database in the cpanel.

You found how to fix it, but not what caused it to fail in the first place.

No, and good point.

I'll need to look into it deeper.

What caused it? mySQL crashed. What caused mySQL to crash? Could be many things. Race condition. OOM. Server failed unexpectedly (no clean shutdown).
Generally one of the log files (system log or mySQL log) will give an indicator as to what happened.
