MySQL has gone away errors...

[pityocamptes]

I contacted my host and they are saying that the issue is on my side, though they can't say what it is, just that's its code, or corrupt DB, etc. Does that sound right? Any suggestions on how to fix this? Thanks.

Invalid SQL:

UPDATE datastore SET
data = data - 60,
data = IF(data < 0, 0, data)
WHERE title = 'mailqueue';
