Re: Why did my HTTP server lock up?

what release?
do you keep up with the http group ptfs?
in over 12 yrs of http (classic & apache) i've only had 1 lock up when running a comm trace and taking heavy traffic on a tiny machine (early v5r3).
And i run maxcgi at 4 times what i expect..
What is your TimeOut value ?
The KeepAliveTimeOut seems way excessive.

Subject: [WEB400] Why did my HTTP server lock up?

One day last week my HTTP server (Apache based) locked up. That is, it stopped responding to requests for both static and dynamic content. It also took a long time to "end", using ENDTCPSVR, before restarting.

Has that ever happened to you?

I looked at my configuration file, and the following jumped out at me:

ThreadsPerChild 10
KeepAlive On
KeepAliveTimeout 3600
TimeOut 3600
MaxCGIJobs 10

That looks like I'm limiting available connections, while enabling persistent connections, and enabling them to remain connection for up to one hour, possibly with no activity.

How smart is that?

-Nathan.
