Mad SQL problems!

[ZomgStuff]

Well I come home and my co-admin tells me there are SQL errors abroad. DB errors that os.

If I click view PM's I get this

Database error in vBulletin 3.6.5:

Invalid SQL:

			SELECT pm.*, pmtext.*
				, icon.title AS icontitle, icon.iconpath
			FROM pm AS pm
			LEFT JOIN pmtext AS pmtext ON(pmtext.pmtextid = pm.pmtextid)
			LEFT JOIN icon AS icon ON(icon.iconid = pmtext.iconid)
			WHERE pm.userid=1 AND pm.folderid=0
			ORDER BY pmtext.dateline DESC
			LIMIT 0, 50;

Error code 28: No space left on device

One or more partitions on your server is out of space or doesn't have enough space to complete this operation. Shutdown your forums (if you can) and contact your host immediately. You or your host will need to find out which partition is low on space and free up some more space.

Thanks, another reason why dot5hosting blows. NEVER buy from them. Site is down all the time.
