Apache 1.3.23 Red Hat 6.2 kernel 2.2.19-6.2.7 and HTTP pausing for 1-5 mins
We started to get some weird pausing on our Virtual hosted Apache web
server. Does any one have any ideas as to what could be happening, or where
to begin looking. I believe its a CGI script on one partiular site but that
have a lot of CGi running, the pausing happens randomly throughout the day,
pausing lasts from 1 to 5 minutes where the HTTP process will not accept any
requests, it comes back on its own, the HTTP process dies not die and
restart. The rest of the server works fine (SMTP, SSH, FTP etc) during
these brief pauses. In the logfile for the web server there is a break in
the log entries when the pausing starts. This server also runs SUEXEC.
This server has been in operation for a year and a bit.
Below is the info from the server.

Hi,
a bit late my post, I know - I had some days off.
Did you try to increase the value for MaxClients?
Your prob looks quite familiar to me.

Again when I noticed this I backed off to Apache 1.3.19 and the same thing
happened, so I knew it was not the newest version so I put it back on after
a few days with the old version of httpd running.

I thought of that as well, but there is no limits on Mod_Throttle, every
virtual host has
ThrottlePolicy None 0 256d set.. We were using it just to monitor bandwidth
and not actually throttling a connection.
I will try and remove it to see if that helps but that has been there for
ages as well.. This pausing started Jan 29 2002

My first guess would be mod_throttle either deliberately or accidentally
limiting connections. Try disabling that and see if the problem goes away.
