I will be eternally greatful to anyone who can point me in the right
direction to solve the following problem with virtual hosts on Apache
httpd 1.0 running under version 1.2.8 of the Linux Kernel as patched for
I had a nice system running here with 27 virtual hosts assigned in my
httpd.conf file. I use the rc.multihome method for assigning virtual
However, 3 more virtual hosts were added on Monday night and the load
averages on our server went out of sight. It was necessary to remove
those 3 hosts from the httpd.conf. They are still in rc.multihome with
Here are the problems I noticed after the load averages went through the
1. The "top" command reveals that there are over 90% user processes on
our system and almost no idle time available.
All of this eventually causes various features like sendmail to stop
working until the system is rebooted or httpd is -HUP'd.
2. CGI pages will not work properly. Performance is very inconsistent,
usually not working.
When the httpd gets a CGI request, its child process becomes a zombee and
that's when the load averages and percentages go through the ceiling.
3. This continues indefinitely until the server basically stops working.
Please let me know if I can help you help me! It is becoming an
emergency since I had to remove those 3 hosts to get the system back to
I also have several more hosts to add. Have I reached a limit
somewhere? Thanks for any help.
