Subject Found it !!! Why is my apache parent process growing...
Date Tue, 03 Jan 2006 15:46:24 GMT
I found it !!!

Issueing an "apachectl restart" (or kill -HUP) make the apache parent 
process size grow !
This is the case on all of our FreeBSD boxes. I can't reproduce it on Linux.

Take a look at this:

apachectl start
# ps aux|grep httpd | grep root
root  70820 59.0  5.6 46408 43552  ??  Ss    4:03PM   0:04.40 
/usr/local/sbin/httpd -k start

So: 43MB right after starting

Now send it a SIGHUP:

# kill -HUP 70820
# ps aux| grep httpd | grep root
root  70820 17.4  7.7 62440 59564  ??  Rs    4:03PM   0:08.48 
/usr/local/sbin/httpd -k start

Wow: the HTTP root process has grown from 43 to 59MB just because I sent it 

On my test box it will take about 50 "apachectl restart" commands, but then 
apache crashes with
a "Out of memory during request" error.

Philip, as you're using FreeBSD too, could you confirm this ?

I'm using a log rotation script which send a SIGHUP to apache every night, 
so that was actually
causing the apache root process to grow.

Thanks anyone for helping me to find this problem !
