Apache stops responding after some days
|
|
Hello List,
I am running apache 2.0.40 with RedHat Linux 8.0. The server is also running
QMAIL and SQUIRREL MAIL. The apache is running only to serve the web mail
requests. The problem is that after running for say 6-7 days the apache
stops responding for some time. After 3-4 minutes it recovers on its own.
During that period the httpd error log reveals that the server was trying to
kill processes that were not in existence. The exact thing is like
"[warn] child process 17130 still did not exit, sending a SIGTERM".
There are several lines like this with different process id. After that we
get
"[notice] caught SIGTERM, shutting down
[Thu Jul 15 12:03:19 2004] [notice] Digest: generating secret for digest
authentication ...
[Thu Jul 15 12:03:19 2004] [notice] Digest: done
[Thu Jul 15 12:03:20 2004] [notice] Apache/2.0.40 (Red Hat Linux) configured
-- resuming normal operations".
Now I have started to regularly check the server status for the last 2 days.
Today I find that there are only 2 processes being served but there are 7
open slots with no current processes. The portion of the status report is
like
Srv PID Acc M CPU SS Req Conn Child Slot

The question is : Is there anything wrong in the present status? Why there
are so many slots with no processes assigned? Is it normal ?
Sorry for this long mail. Actually I am a novice and don't know how to
proceed. Please guide me.
With regards,
Goutam
