xf_session needs repairs now and then... why?

[andrewkm]

After restarting my VPS / and other random times... my xf_session tables shoots off an error and the forums simply don't work.

Mysqli statement execute error : Incorrect key file for table './andymidu_xen/xf_session.MYI'; try to repair it

The only thing that fixes it is a repair on that table through phpmyadmin. Any ideas why this happens so often?

I have the same issue often. Why?

Superficial corruption can happen when a service or server crashes or unexpectedly shuts down in the middle of a write. It's nothing to worry about unless it recurs, then you need to examine your uptime and logs to see what's going on.

Check your Disk IO, upgrade to SSD if needed.
