following is my server environment information:

OS: Suse Linux 10
Web: PHP5.24 and Apache/2.0.63

The attachments is my httpd.conf and virtualhost.conf

please help fix it , thanks a lot.

In your config:

<IfModule prefork.c>
StartServers         5
MinSpareServers      5
MaxSpareServers     10
MaxClients         150
MaxRequestsPerChild  0
</IfModule>

# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule worker.c>
StartServers         2
MaxClients         150
MinSpareThreads     25
MaxSpareThreads 75 ThreadsPerChild 25
MaxRequestsPerChild  0
</IfModule>

# perchild MPM
# NumServers: constant number of server processes
# StartThreads: initial number of worker threads in each server process
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# MaxThreadsPerChild: maximum number of worker threads in each server process
# MaxRequestsPerChild: maximum number of connections per server process
<IfModule perchild.c>
NumServers           5
StartThreads         5
MinSpareThreads      5
MaxSpareThreads     10
MaxThreadsPerChild  20
MaxRequestsPerChild  0
</IfModule>

That, in my opinion, is an insane amount of spare threads to have. Do you really need 25-75 spare threads for your workers?
