you see an error similar to the following, it could indicate that your server has run out of semaphores. semget: clear apache semaphores No space left on device To see how many semaphores are being used, SSH to your server as root and run the following: ipcs -s In order to get Apache started again, we

must clear the semaphores. Run this for-loop to flush them: for whatever in `ipcs -s | awk '{print $2}'`; do ipcrm -s $whatever; done On older servers that command may not work. In these cases, you may need to do the following: /sbin/service httpd stop

/sbin/service httpd start If couldn't create the mpm-accept mutex this is a common problem for you, you may want to increase the semaphore limits on your server. You can do that by adding the following to the /etc/sysctl.conf file: # Increases the semaphore limits & extend Apache's uptime.

Description Kevin Hawkins 2004-01-20 00:03:30 UTC I just compiled 2.0.48 with mod_proxy included. I have two httpd's already running, listening to different ports, and all config files test Syntax OK. The first two are running fine: # cat /usr/local/apache2/logs/httpd.hawk.pid https://bz.apache.org/bugzilla/show_bug.cgi?id=26265 4157 # ps ax | grep 'httpd' | grep 'hawk' 4157 ? S 0:00 bin/httpd -f conf/httpd.conf.hawk 4158 ? S 0:00 bin/httpd -f conf/httpd.conf.hawk 4159 ? S 0:00 bin/httpd -f conf/httpd.conf.hawk 4160 ? S 0:00 bin/httpd -f conf/httpd.conf.hawk 4191 ? S 0:00 bin/httpd -f conf/httpd.conf.hawk 4192 ? S 0:00 bin/httpd -f conf/httpd.conf.hawk # cat /usr/local/apache2/logs/httpd.immuno.pid 4143 # ps ax | grep 'httpd' | grep 'immuno' 4143 ?

S 0:00 bin/httpd -f conf/httpd.conf.immuno Now trying to run a third so that I can proxypass to it from the first one. When I run httpd with my custom config file, I do not get any errors on the commmand-line, but this shows up in the error log: [Mon Jan 19 15:19:22 2004] [emerg] (28)No space left on device: Couldn't create accept lock Apache did create the lock file (which is specified in the config file and is on a local filesystem), and it's exactly the same as the other two: # dir /usr/local/apache2/logs/ total 24 drwxr-sr-x 2 root root 4096 Jan 19 15:19 ./ drwxr-sr-x 15 root root 4096 Jan 19 14:00 ../ -rw-r--r-- 1 roo

Check if there’re any processes in semaphore that are owned nobody in semaphores.Code: [Select][b]# ipcs -s|grep nobody[/b]
If you can see the semaphore processes for nobody, eventhough no apache processes are running, you can remove them safely. It happens when Apache dies without clearing the Semaphore arrays.We can run the following command to remove it safely:Code: [Select][b]# for semid in `ipcs -s | grep nobody | cut -f2 -d" "`; do ipcrm -s $semid; done [/b]
Now restart the Apache service.Code: [Select] [b]# service apache restart [/b] Logged Print Pages: [1] « previous next » Admin-Ahead Community » Linux » General Linux » Apache Error: No space left on device: Couldn’t create accept lock SMF 2.0.11 | SMF © 2015, Simple Machines XHTML RSS WAP2
