Having to restart mysql every day

I’m trying to evaluate pimcore but the site keeps dying and i have to keep restarting mysql. Does anyone know if there is a mysql tidyup job installed with pimcore that could be causing this. The timing is random but always has something like below in the mysql log.
It looks like something keeps restarting the mysql service but sometimes fails. I have other ubuntu/php/mysql servers running but not with pimcore and not with the log entries as below.
This was the last of 5 retries, 21 mins earlier it had done the same thing but not got the buffer pool error and restarted ok.
