All of a sudden, blog is blank

Hello,

I am running two wordpress blogs, one using wp 2.1.3 and one using 2.2, using the same database but different tables for each one.

Everything was fine until this morning, when both blogs stopped displaying pages. No errors, no partial HTML, just blank pages (e.g https://heathergold.com/blog).

I’ve been trying to track down the issue, but I’m not a WordPress expert by any means (though I’m starting to get there as I trace through code). I hope that someone can help me with some suggestions.

Here are some of the symptoms:

– No errors appear in the apache error log
– I tracked WP execution through our custom themes, and found that the app craps out in different places some of the time (sometimes while including a file, sometimes while trying to make a call to the database)
– The database is about 40MB in size, about half of which is the spam karma spam table
– I did manage to get one error to show up:

`# ack! query failed: errorno=2008
# error=MySQL client ran out of memory
# query=SELECT * FROM docs WHERE doc_id = 1`

I thought I would try to upgrade WP and switch to a vanilla theme, but since I can’t get to the admin screens, I’m having a hard time finding documentation for how to do that.

Any suggestions for what to try next?
