More info..
The problem is seen with 2.0.55. It wasn't seen with 2.0.53. Haven't tried 2.0.58 or 2.0.59 yet. The change log for 2.0.58 doesn't seem to indicate any fix for this problem.

Hi,I notice there is a 100% CPU utilization which spikes for sometime and then goes back to normalcy when Apache is used a reverse proxy. I noticed a mail thread which seems to be a similar problem http://mail-archives.apache.org/mod_mbox/httpd-dev/200510.mbox/[EMAIL PROTECTED].One thread of one of the child processes hangs, calling poll() and writev() system calls so frequently that it causes 100% CPU util. The thread is trying to writev() to a socked which is in CLOSE_WAIT The child process ends after time defined by ndd parameter tcp_keepalive_interval and the same service time can be seen in access_log. The problem disappears then.
