I recently recomplied the apache20 port (updated) with no compile-time
changes. Since that time, I noticed it was hogging 98% of the CPU and
hanging. I adjusted the various Max/Min server levels and that seemed
to fix it - except at midnight when the logs are rotated and the server
is sent a HUP signal. When that happens, all the processes die except
one and it hangs at 90% CPU. I kill it off, restart it manually and it
Here's a recent output of "top" :
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
94711 www 1 117 0 41036K 13852K RUN 0 1:43 98.69% httpd
The only thing that has changed on the system is an upgrade from
MySQL-4.1 to MySQL-5.1, which I wouldn't expect httpd to be affected by,
but I could be wrong. To be sure, I recompiled it, PHP and any
dependencies that PHP has, but I'm still seeing the same result.
I tried compiling MySQL-5.1 with and without pthreads and see the same
CPU consumption issue.
I wonder if I've hit a bug or if I've possibly messed something up (as
careful as I've been anyway).
