My server just hit the skids last night (mysql CPU usage went though the roof and stalled page load times to about 30 seconds). I'm running VB 4.0.2 - and it's been stable for about 6 months.
I've flushed logs, and checked all tables, etc.
I noticed that the searchcore tables look odd by displaying a negative number. is this the way it is supposed to look? I also have negative searchgroup numbers, but they are much lower in the 300K range. The forum also has 4.6M posts, but that table seems to look ok.
