Unexplained unresponsiveness of Apache httpd

["Raj Iyer" <Rajalakshmi.Iyer@xxxxxxxxxxxx>]

Hello,

 

I am currently dealing with a situation where the Apache httpd process becomes unresponsive for some time. At the end of this time, the Apache error log shows:

 

[Mon Nov 2 13:27:49 2009] [warn] child process 7310 did not exit, sending another SIGHUP
[Mon Nov 2 13:27:49 2009] [warn] child process 27558 did not exit, sending another SIGHUP
[Mon Nov 2 13:27:49 2009] [warn] child process 751 did not exit, sending another SIGHUP

. . .

[Mon Nov  2 13:27:50 2009] [warn] child process 7164 still did not exit, sending a SIGTERM

[Mon Nov  2 13:27:50 2009] [warn] child process 13494 still did not exit, sending a SIGTERM

[Mon Nov  2 13:27:54 2009] [error] child process 26222 still did not exit, sending a SIGKILL

[Mon Nov  2 13:27:54 2009] [notice] SIGHUP received.  Attempting to restart

 

After this restart, the process resumes normal operation.

 

I would appreciate any assistance in debugging this problem.

 

Thanks,

Regards,

Raj Iyer
