MySQL server has gone away

That error is caused by one of these MySQL settings being exceeded:

wait_timeout
max_allowed_packet

Your host or server person needs to increase these settings in MySQL. There is more info here:

That error is caused by one of these MySQL settings being exceeded:

wait_timeout
max_allowed_packet

I made changes ( wait timeout = 28800 а max_allowed_packet = 48M ), but the error still appears...

[Paul B]

You seem to have several crashed tables: xf_search_index, xf_session, xf_session_admin.

You will need to repair them or truncate them and in the case of the search index, rebuild it.

Perhaps the reason in MediaWiki...

I'm not sure what you're specifically trying to show with those kernel (/var/log/messages) logs, but it clearly shows MySQL is being killed because your server is out of memory. At the least, you'll need to tweak various settings regarding to memory usage by various programs. Alternatively, you may need more memory. (There's always swap space, though that might just create performance issues in a situation like this.)

If MySQL is killed without going through the normal shutdown process, corruption is very possible.
