Apache acts funny and big problem

[bjarne]

SSL on APCHE is a mess

Almost as soon as apache is started I get a cpu that maxes out the cpu (glad we have hypertread P4) and there is a root owned process in top, eting the cpu power.

Anyway I decided to rebuild apache with no SSL support, and it looks like the problems are gone. As far as the unstable stuff.

Something is wery wrong with this apache and I do belive it is relatet to ssl and some kernel stuff.

After doing killall -9 httpd every 5 min for 12 hours apache gave this error: semget: No space left on device and I had to restart the server to get it up agian.

I conclude that something ssl relatet is the problem, because it helps to recompile with no SSL, now it has been up for more then 8 hours and it looks good.

Hi dude!!!

This is not an issue with ssl. Run the following two commands from the root shell.

ipcs |grep nobody | awk '{print $2}' >> /root/semget
for i in `cat /root/semget`; do ipcrm sem $i;done

Restart your apache.
Enjoy!!!

ipcs |grep nobody | awk '{print $2}' >> /root/semget
for i in `cat /root/semget`; do ipcrm sem $i;done

What's for are those commands?

The "commands" is a workaround to clear your shared memory without rebooting. You can find a "segmentation fault, cannot write to device" error inside your apache error_log coz ur shared mem is full. ipcs shows the share memory segments, Semaphore Arrays and message queues. The commands clear this using the "semid"s used by nobody (apache). Dats aaall.

Hi Vibz,

Any idea how to find out, the real cause of that issue? Because it's happening for me everyday... And I have to clear the semaphores owned by nobody everyday... I can write a cron for doing that.. But do you know any way to find out the root cause of the issue and thereby fix it....

Hi amal,

I'm sorry, i dont know. Probably you'll have to escalate this to the cpanel team.

bugzilla.cpanel.net or #cpanel on efnet.

Use them wisely.
