The problem is that some random members have had their post count jump to 16777215.
I'd venture the guess that the post count is stored in a 3-bytes unsigned variable (strange but why not...), that they had 0 posts, and that the forum remorselessly tried to decrement the post count. ( -1 == 16777215 [3 bytes]) (I don't know PHP, but I assume it deals with out-of-range assignments the same way C++ does)
Maybe they had only posted in a forum where the posts are not counted, then you moved their posts, and deleted one of them. Or something of the kind...
It would be interesting to try and reproduce that bug, although it has probably be found and fixed in CVS. I hope. If it has not, it definitely qualifies for a bug report.
