Delayed Upvotes: SegFault in MySQL Server

There was a 8 hour delay in daily upvotes, and also the ranking page stats. It was caused by MySQL crash and unfortunately, I was asleep, and also the auto restart didn't fix it.

Here is the logs from /var/log/mysql/error.log
It suggests a Bug or a Hardware Failure.

00:13:25 UTC - mysqld got signal 11 ;
Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
