Hope this isn't too OT, not sure if it's specific to
FreeBSD or not (I found both suggestions in searches).

I'm running Apache/1.3.22 (Unix) PHP/4.0.6 mod_ssl/2.8.5 
OpenSSL/0.9.6b on FreeBSD 3.5S.


My webserver appears to use more and more swap as time goes
by. I've watched this via top and swapinfo. Graceful restarts
take care of things (frees up my swap). If no restart is
issued, apache will continue to eat up all swap and all other
processes have no memory to work with (choke --> die). I've
been lucky enough to spot it and restart before a full server
crash (I've heard this will happen). I find nothing in the
logs. I moved one of our 'heavy users' to another box and the
problem all but disappeared. I have a program running now that
monitors my swap and restarts apache, but clearly, that is not
the best solution. The site I moved did have some good sized
http file downloads (if that helps any other diagnostician).

Sure does act like a memory leak.


Grateful for any clues.


TIA,

mike
