Hi Do you mean that looping email would be the source of the problem?
I haven’t seen any looped email in our system. Also I have defined all email address in $RTAddressRegexp. So I think it would prevent loop. Isn’t it?

I disabled $LoopsToRTOwner and the problem disappeared. I didn't have time to debug the issue further... -- Mathieu Longtin 1-514-803-8977 On Sun, Mar 20, 2011 at 4:19 AM, Payam Poursaied <m...@payam124.com> wrote: Hi all We are using rt3.8.8 and we faced with a problem using apache 1.3.42 on FreeBSD 8.0-RELEASE. The problem is that httpd processes frequently reach 100% CPU usage and stay at this level of CPU usage. This is a sample of top output.

I tried to compile apache in debug mode and then wait to see a suspicious process and then attached GDB66 to that cpu intensive httpd process to find out what is going on. But I could not go further more. I have also consulted with apache-freebsd mailing list but there wasn't any success. Could anyone help me to drill down this problem?
