I've noticed this happen several times in the past. It would have 150
hung connections but not very high cpu or network usage. On those
occasions I restated httpd to get things going again.

Looking at the httpd access logs it looked to me like an errant indexing
bot. One example of something we might want to ban bots from is from
accessing all past revisions and diffs of wiki pages. But generally we
probably just need to look at the logs and try and see what's going on.
