[users@httpd] Apache restarts on logrotate

["Chidanand Gangur" <chidanand.gangur@xxxxxxxxx>]

Hi all,

I have configured apache with php and ssl. I have statically linked
them in apache and using it for an embedded application. I have also
configured logrotate to rotate the log files when the
access_log/error_log reaches to 5M.

I am using apache-1.3.34.
 
Many times I see the following message in my error_log file.

[notice] SIGHUP received.  Attempting to restart

after googling I found that SIGHUP is sent by logrotate when it clears and backups the file.

I see this event every often. 

Does the process actually get restarted,  or is reloaded?

Some times I see that apache process hangs with limit of MaxClient
reached. This condition sometime recovers over the period of time and
some time does not.

Is that the frequent restart of apache process causing this problem? 

When the condition arises I also tried to do netstat I see lot of
stream sockets in connected state. UNIX stream sockets are openened in
PHP script to talk to othe r modules in the system.
