Hi Guys,

I've been experiencing a strange problem with our FreeBSD web server:

FreeBSD www.piyeepress.com 4.8-RELEASE
Server version: Apache/1.3.27 (Unix)

When accessed via a web browser, it will return pages for a few minutes.
Eventually access is super super slow, as if some TCP state table is
filling up.  I reboot the server and it returns web pages as it should,
but only for five or so minutes, when it won't return any more pages, or
it returns pages but very slowly.

I've tailed the apache log and the page is returned when I see it appear
in my web browser.  I'll click on a link, wait a minute or so, and if the
page does finally appear in the browser, only then do I see the access in
the httpd log.  Same type of thing with tcpdump.  Using rules and a few
regular expressions to show just my IP, I don't see anything until the
actual webpage comes through on my screen.

The output of netstat -ap tcp doesn't show too many open
states.  I swear that some tcp state table is filling up;
otherwise I have no clues.  Here's something too: if I use lynx to access
the site, and I access the site from another server in the same rack, the
page is returned instantly.  Here's some more confusion: non-Windows
machines seem to do better at getting pages from the server than do
Windows machines.

Any ideas?  Sorry if I have been unclear.  This problem has been driving
me crazy!

Thanks,

Chris Kelly
