Problem reproduced on:
Red Hat Enterprise 3, 2.4.21-37.EL
With apache 2.0.55 and 2.0.58 compiled from source tarballs with MPM "worker"
configure options:
--with-mpm=worker \
--with-perl \
--prefix=/usr/local/apache2.0.55 \
--enable-mods-shared="most info proxy proxy-http proxy-connect ssl" \
--enable-so
The server was configured with several virtual hosts for both HTTP and HTTPS sites.
Commenting out VirtualHosts definitions and Listen directives for SSL (i.e. let
the server listen only on port 80 and not on both 80 and 443) and restarting or
making a graceful (with apachectl) causes CPU *and* disk usage to increase.
A hard reset/shutdown is needed because of the very high load caused.
Is the attached patch known to resolve the problem? why it's not been included
in the main sources yet?
