Subject: Re: httpd/sshd will not start due to "failed to create proxy mutex" error

Hi , i am using "Mutex sem"

if i using Mutex posixsem proxy, came out 2 errors:
1 .watchdog-callback (fixed by using Mutex sem)
2. Failed to lookup provider 'shm' for 'slotmem': is mod_slotmem_shm
loaded (fixed by uncomments conf file )

I fixed it!  I don't know if the fix is any good, but the server
starts and serves pages.  The key was this Mutex directive:

https://httpd.apache.org/docs/current/mod/core.html#mutex

I wound up adding this to my httpd.conf:

> Mutex posixsem proxy

I don't know if "posixsem" is the right choice, but it seems to work.
All of the choices have warnings that make them all sound horrible:
dizzyness, depression, erectile dysfunction...but we're going to try
this.  I'm just developing on my local system, anyway.

Cheers,
Matt
