When starting Apache we are getting this message: No space left on device: apr_proc_mutex_lock failed
I saw this thread:
http://forums11.itrc.hp.com/service/forums/postQuestion.do?categoryId=156&forumId=1
But Glance tells me we are no where near running out of any of the listed kernel params, memory, swap or anything else. Has anyone received this message and found it to be caused by any other kernel params or outside sources?
We are running Apache 2.0.47 bundled with Websphere on HPUX 11.11.
Thanks!
Solved! Go to Solution.

Re: No space left on device: apr_proc_mutex_lock failed
The "No space left on device" refers to a filesystem that is full.

Re: No space left on device: apr_proc_mutex_lock failed
It appears that Apache will also report "no space on device" when it hits kernel limits as well.
Thanks!

SolutionHere is a set of "recommended" kernel parms for apache - I can't say they are right for you, but if any of yours are significantly elow these numbers you might want to adjust them up:
maxdsiz (recommended value 0X40000000)
maxssiz (recommended value 0X17f00000)
maxtsiz (recommended value 0X40000000)
max_thread_proc (recommended value 2048)
maxuprc (recommended value 512)
nproc (recommended value 2048)
nkthread (recommended value 6000)

Re: No space left on device: apr_proc_mutex_lock failed
I suspect maxssiz and maxtsiz may have had the most impact as they were still set at defaults so the increase was huge.
Thanks!

Re: No space left on device: apr_proc_mutex_lock failed
maxtsiz has no impact since nobody writes programs that large.
I would suggest you put back maxssiz since this will decrease maxdsiz. You don't need 400 Mb for your stack size.
