Subject [users@httpd] Unable to open logs - but NOT a permission problem
Date Mon, 25 Feb 2013 17:03:07 GMT
I have been scouring the net for my specific issue.  All the responses
suggest that either the file permissions are wrong or that the ulimit
is set too low.  I know that neither of these is my problem because
Apache starts at boot and sometimes restarts while the server is
running.  While it is running I seem to be able to kill -1 as often as
I want.

However, if the server stops for any reason, there is a good chance
that it won't restart and gives me the "unable to open logs" message.

I am running NetBSD 5.1.  Here is some info from sysctl relating to
number of files:
 kern.maxfiles = 52364
 proc.curproc.rlimit.filesize.soft = unlimited
 proc.curproc.rlimit.filesize.hard = unlimited

An fstat | wc -l gives numbers an order of magnitude below maxfiles.
Currently, even with Apache running, it is sitting at 7638.  When I try
to restart my ulimit is unlimited.

Here is my memory usage currently.
MemTotal:  16252760 kB
MemFree:   14894768 kB
MemShared:        0 kB
Buffers:     304496 kB
Cached:      799904 kB
SwapTotal:  8389548 kB
SwapFree:   8389548 kB

Here is more information about my system:

As for log permissions, here are all the files and directories,
including parents, with today's timestamps.

As you can see I am running suExec but this problem happened before I
implemented that.  In fact, suExec allowed me to run one server instead
of multiple ones.  I was hoping that it would solve my problem by
reducing resource usage but no joy.

I can't imaging what other information I can supply here but if you
need more please let me know.  This machine takes five minutes to
reboot so I would really like a way that does not involve booting.

Any help really appreciated.
