One of our systems run Apache 2.0.52 (httpd-2.0.52-12.2.ent.centos4
rpm). The kernel we're running is 2.6.9-11.ELsmp. After a few weeks
of uptime, Apache refuses to start with the following error in
error.log:
[crit] (28)No space left on device: mod_jk: could not create jk_log_lock
With Apache not running, there're a lot of semaphores left behind by
Apache, e.g.:
------ Semaphore Arrays --------
key semid owner perms nsems
0x00000000 98304 root 600 1
0x00000000 131073 apache 600 1
0x00000000 163842 apache 600 1
0x00000000 196611 apache 600 1
0x00000000 229380 apache 600 1
0x00000000 786437 root 600 1
...
...
...
/proc/sys/kernel/sem has the following settings:
250 32000 32 128
Is this an Apache issue or is this a kernel issue? Why is Apache not
releasing the semaphores?
Thanks for any help.
I've no idea what causes it, but this is how I solved it: http://www.sagonet.com/forums/showthread.php?p=14635#post14635 Someone else know why this happens?
