WordPress MU

Help Please!!

Something is happening to an MU install. Up untill november everything has been going fine..

November 1 to present, there is something going on where a page will load and will get stuck loading a post and will just drain all the memory of the server resulting in all http services going down. I have been able to temporarily manage this by changing the dates of the posts to October dates but my time is running out and I need a fix.

Please anyone any leads or any info would help thanks.

Are you sure it's date related ?
I've seen this issue happen, and my problem was that some category had its parent category set to itself somehow, which was making MU start an infinite loop.
