MySQL Error : Out of memory (Needed 1048548 bytes)

This is the key thing here that was causing things to go boom.
What this is saying is that something, somewhere is using up too much memory, you don't have enough, or something along those lines.

If you're on a shared host, contact your host and have them find out what the problem is. Maybe they've put some unusual memory restrictions on your account, maybe something else entirely.

If you're on a ded server, you've got three options:
A> Find out what's killing your memory and kill the application.
B> Upgrade memory (not going to work if something is hogging all your memory, it'll just keep disapearing)
C> Hire a server manager to handle these kinds of things for you.
