I have a condition in my network where all of a sudden the server becomes

I am using PHP for server side scripting where I open UNIX dgram socket to
comunicate to the back end. I have a test where 800-1000 user try to access
the server.
I see lot of UNIX stream sockets in connected state in net stat though I
am using UNIX dgram sockets. I also see the apache has reached MaxClient
limit of 250.
When such condition arises I see whole of my system becomes slow.
I want to get a clear idea where things are messing up.
If you want to look at the scoreboard, use the server-status handler
provided by mod_status. This won't, of course, help if your server is
completely locked up. But I don't think you're going to get anywhere
trying to debug the raw scoreboard. And it doesn't seem to have
anything to do with your problem.
Obviously if you have 1000 clients connecting and MaxClient of 250,
you're not going to get much performance. If you want to really see
what apache is up to, use a debugger as described here:
