We have strange thing happening on a freshly installed and patched
server.  Apache 2 will come up on boot, but then after that, it will
not start again if for some reason it is stopped.  We have hundreds of
similar installs and have never had a problem, but something is a
little different on this one.

Here is the error that we get in the error_log when it tries to
restart:
[emerg] (38)Function not implemented: Couldn't create accept lock

And here are the versions:
SUSE LINUX Enterprise Server 9 (x86_64)
PATCHLEVEL = 3
apache2-prefork-2.0.49-27.59
kernel-smp-2.6.5-7.267

Any help would be appreciated.

IIRC this is commonly caused by running an Apache is compiled using
with headers from a different kernel version (something to do with
shared memory semaphores). Try using ipcs before starting Apache, and
again after stopping it to see if its cleaning out the semaphores
(ipcrm to confirm).

How you fix it depends on how you got in this state.
