Re: Long running Apache 2.2 process

["Chandranshu ." <chandranshu@xxxxxxxxx>]

Hi

We have now turned on mod_status and added the "ExtendedStatus On" directive to httpd.conf and have restarted apache gracefully. However, there is no information about the rogue process. I guess this is because that process was forked before this directive was turned on.

Anything else we can try to track the request being served by that process?

Thanks and regards

Hi

We are running Apache 2.2 and have setup PHP-CGI to serve PHP files. Today, we observed that a php-cgi process has been running for a very long time and is consuming 100% CPU. The parent apache process of this php-cgi has been running since July 26th. We do a graceful restart of the server every hour to pick up new virtual host connections but apparently, this process has not been reaped till now.

Is there a way to figure out what request this apache process is serving?

I have tried looking up on Google and found apachetop but that doesn't give us the required information.

I have also tried to locate the file being executed with 'lsof -p <pid of apache and php-cgi prcoess>' but that listed mostly the dynamic libraries. The peculiar entries in the php-cgi case were:

php-cgi 16665 swarLD21606    0r  FIFO    0,6           2605128 pipe                                                               
php-cgi 16665 swarLD21606    1w  FIFO    0,6           2605129 pipe                                                               
php-cgi 16665 swarLD21606    2w  FIFO    0,6           2605130 pipe                                                               
php-cgi 16665 swarLD21606    3u  sock    0,5           2605937 can't identify protocol

and in the case of httpd was:
httpd   16414 apache  558u  sock    0,5            2605127 can't identify protocol

which we haven't been able to explain.

Any suggestions to investigate will also be very helpful.

Thanks and regards
