Apache becomes unresponsive

Hi,

I am running Apache 2.0.48/PHP 4.3.4 on Sun V240 box. I am generating
20 requests/sec to Apapche which forwards it to my PHP page. After a
while I see all the threads waiting to send reply (Apache
server-status shows "w") and Apache becomes unresponsive. Following
this I see "Reached MaxClients ...." message in Apache's error log.
Has anyone seen this before? I would appreciate if somebody can help
me with this.

Thanks,
Atul

In your config files, you have a setting for max_clients to what .. 100?
Increase it to something that fits your needs a lot better.

I'm personally unsure what it's about exactly, but www.apache.org
documentations will tell you specifics about that directive.
However, it's my assumption that with 20 requests/second you should be at
about 400 max_clients, assuming your php pages are served within 4 seconds
....

Else you have to go higher.

HTH,

Andreas
