server reached MaxClients setting

[finalwebsites]

Hello,

after a few month I get back this problems, Apache stops working need to be restarted etc.

I have a 3 ghz/ 2GB amd athlon server and have this cofiguration:

# prefork MPM
# StartServers ......... number of server processes to start
# MinSpareServers ...... minimum number of server processes which are kept spare
# MaxSpareServers ...... maximum number of server processes which are kept spare
# MaxClients ........... maximum number of server processes allowed to start
# MaxRequestsPerChild .. maximum number of requests a server process serves
<IfModule prefork.c>
StartServers         5
MinSpareServers      5
MaxSpareServers     10
MaxClients         256
MaxRequestsPerChild  0
</IfModule>

# pthread MPM
# StartServers ......... initial  number of server processes to start
# MaxClients ........... maximum  number of server processes allowed to start
# 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         200 
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 (then it dies)
<IfModule perchild.c>
NumServers           5
StartThreads         5
MinSpareThreads      5
MaxSpareThreads     10
MaxThreadsPerChild  20
MaxRequestsPerChild  0
AcceptMutex fcntl
</IfModule>

which is the best configuration and where can I see which of those 3 is used?
Thanks...

Partition details needed

Hi,
Our company plan to setup a own hosting server. We purchased the server with configuration of Xeon Dual core processor,with 300 GB Harddisk.

Kindly suggest the best partition details suitable for Plesk 8 control panel in our server installed Federo 5.

thanks.

Yeah that was kind of bizzare huh?

So if I follow the problem you're having is that apache will be running, but wont be responding to any new requests right?

can't say that exactly because watchdog is restarting the whole thing, do you need some log information?

 

[atomicturtle]

Ah, so apache is actually dying periodically? I can think of a zillion things that could do that (you're being attacked/DDoS'd, bad mod_rewrite rules, etc). What distro are you on?

I'm running a debian distro... check this thread I think thats similar to my problem:

Ah, Im not familiar with the eccentricities on that implementation, Id check with the debian support groups first. Configuration debugging-wise a good place to start would be to disable everything plesk-related that you can (sitebuilder, tomcat, etc) and see if it goes away. If it does, then you can nail it down to one of the PSA components.

For now I raised the timeout limit to 30 seconds and I got no more watchdog messages

look, it's important for me that my server works for the next 6 weeks. After that time I get a new one with also a better partner.

Thanks!

look like still the same problem:

this is the error log during the last restart:

[Fri Mar 23 07:56:23 2007] [notice] caught SIGTERM, shutting down

so again what should I change in the configuration above? and is the apache restarted by apache or watchdog?

thats the watchdog message:

The Web Server (Apache) service on host localhost.localdomain is down.
The problem was discovered on Mar 23, 2007 07:56 AM.

and the server was really down for a while because I got also a message from an external monitor service.
