Hello -stable:
Is anyone else here having an out-of-swap condition, apparently
caused by apache2?
This has only been happening since about the end of June.
It seems to start about 24 hours after the system has been
rebooted after a cvsup/{build,install}world.
OS is -stable, as of 2002/07/05; this started happening (I
think) after some port-updating (apache2) on 28 June.
Webserver is apache2, from -ports, along with mod_php4.
Apache/2.0.39 (Unix) DAV/2 PHP/4.2.1
While this event is underway, top shows httpd at the top
(eating quite a lot of CPU) & with a status of "PFAULT"
(or something like that). After the event "finishes" httpd &
the system appear to be running again, just fine.
Looking around in the logs, I find the following:
From /var/log/messages:

hopefully not embarrass the guilty... :)

Anything else in the logs is several minutes "outside" these
(perhaps related?) entries.
DNS is cache-only:
named 8.3.2-T1B Fri Jul 5 19:08:16 CDT 2002
root@localhost.my.domain:/usr/obj/usr/src/usr.sbin/named
Any ideas as to what might be going on here?
The above is, to me, admittedly rather sketchy; any suggestions
as to how I might trigger this myself & capture any more helpful
logging/debugging data/info?
Is this even a FreeBSD issue? i.e. Should I take this up with
the Apache Group? Or is this some kind of pilot-error on my part?
Many thanks,
-kc
