It looks like I'm running MySQL 5.1.42 (should I upgrade?), MediaWiki 1.14
The mysqld logs do not show any errors (or other significant messages). It does seem to die overnight, so your memory issue might be the cause. Time to look in the MySQL manuals.

Hello,
I think this is more a mysqld error than a mediawiki error, but do you have some info that could help? *mediawiki version *mysql version
Does the log say anything more about why it stops? I had a problem like this also a while ago. In my case the mysqld was using to much RAM every night and that killed the mysqld.
