User Post Count goes to 4294967294
 

I have a situation where every so often some random user's post count will go from zero to 4294967294. I suspect what is happening is that something is deleting a post from someone who has 0 posts resulting in a -1 which then gets translated into 4294967294. Any idea what might be causing this or how I can track it down? I have asked users who this has happened to if they did anything in particular on the site such as uploading a photo, deleting an attachment, etc. and either people don't remember doing anything or they claim they didn't even visit the site.

This problem is more of an annoyance than anything but I'd sure like to be able to track it down to its source but I'm not sure how to do so or where evidence of what is happening might show up.

Thoughts?
