"Resource Limit Hit" message every hour!

[Jessica.C]

Why do every hour (started at 12:56 pm) I get the "Resource Limit Hit" message? I mean, I understand why I'm getting the message, but it's happening EVERY hour. It came up at 1:58, then 2:58, and just now, at 3:58. after a few minutes it goes away.

just started today. never happened yesterday or previous days

My guess is you're hitting the resource limit just prior to the -end- of the hour, and then because it resets every hour, it undoes itself only a few minutes later.

Is it possible that's when googlebot/yahooslurp/other search engine robots are choosing to index the page? If so that'd explain it, as they tend to view -every- available thread and post that an unregistered user can see, so it can easily be a few dozen page views on a small forum.
