XF 1.5 Mysqli statement execute error

Every now and then I login to the ACP and find this error. What does it mean, and how do I fix it?

This can happen when the MySQL server is particularly active, generally when backups are running. There are a couple of configuration values within it that can be tweaked. See my post here: https://xenforo.com/community/threa...nt-needs-to-be-re-prepared.63797/#post-674450 Otherwise, unfortunately it can't really be resolved within XenForo.

Appreciate that, I will give it a go!
