I *think* but am not certain that this is more frequent on large pages. They
also tend to occur in clusters (with respect to time). Certainly they are not
limited to srv5.

This is still happening. I got this error twice today, each time when trying to
save an edit, within a few minutes of each other. The pages were not
particularly large, I don't think. It's off-peak and the site is otherwise
quite responsive, so I was a bit surprised. Example:

Request: POST
http://en.wikipedia.org/w/index.php?title=Rotation_group&action=submit, from
0.0.0.0 via bayle.wikimedia.org (squid/2.5.STABLE12) to en.wikipedia.org ([unknown])

Another burst of these. The only unusual activity I can see on ganglia is
bursty network activity on bacon. Is it possible a network segment is being
overloaded?

As far as I know these are under control now.
