[users@httpd] Httpd processes are not dying
Hi Joshua,
I am not sure you remember the problem I stated last time so I am
listing it here again. You had asked me to run mod_status. I have
attached the output of the mod_status too.
Problem: The httpd processes keep getting accumulated in the memory and
are not dying timely as expected. This happens even when there is no use
of the application for hours. There are times when we see more that 70
such processes even when application has not been used for 6-7 hours.
Since these processes donot dye in timely manner, they keep getting
accumulated till the MaxClient limit is reached and at that point I.H.S.
stops responding and thus site becomes down. We then need to restart the
I.H.S. server. We have been experiencing this problem since we migrated
to WAS 5.0.2 / I.H.S. 1.3.26.2 combination.
Following are some of the parameters in the httpd.conf file that you
would like to know -
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
MinSpareServers 1
MaxSpareServers 5
StartServers 1
MaxClients 300
MaxRequestsPerChild 0

Well, the server-status looks completely normal except that
MaxSpareServers is not being honored. So the first thing I'd do is
triple-check that you are editting the correct config-file, and that
MaxSpareServers occurs only once in that config.
Other than that, I'd really suggest reporting this to IBM, since it
appears you are using an IBM-modified version of the server.
Joshua.
