I've got an RT installation (RT 3.2.1 Apache/1.3.29 (Unix) mod_perl/1.27 mod_ssl/2.8.16 OpenSSL/0.9.7c running on Linux version 2.4.24-ow1 w/ 4x Xeon 3GHz & 2GB RAM) which is exhibiting very high (99%) CPU load on the parent process. This behavior is intermittent, I'd say the parent process spends 80% of it's time at 99%.

I'm not a newbie, but have never personally seen this behavior before. Googling for "apache parent process high cpu" hasn't turned up much.
