mysql error - host says can't find problem

[kokopoko]

I'm having a big problem right now with one hosting company. Every domain I have on that host that uses mysql in some way (WP blog, Linkwit, Asrep) is giving mysql error 28.

This error means you're out of storage space or the temp directory where mysql writes is out of space. Except my host server admin says there is lots of room plus it's only me with the problem.

Is it possible for only one account (not one domain but all domains one person has) on a server to have the mysql error 28 problem? If so, how the heck do I fix this? Every domain has enough disk space.

I don't have access to do any of that on those pages. I sent it to the server admin though. Hopefully he can fix everything.
