Hey all,

After quite a few hours I managed to get ZM working, however after a reboot I'm back to square one with this error in the syslog:

Apr 7 17:44:15 noc zmu[390]: ERR [Can't shmget, probably not enough shared memory space free: Permission denied]

I'm sure this is the error I got before, but I can't remember how I fixed it. I've tried increasing the shared memory available as the FAQ suggests, but it's still not working. I'm sure it's just a really small permission error, but I'm unable to get any further debug information.

Any help would be appreciated!

Thanks

Possibly you created the shared memory as root (as would be normal) but now you're trying to run as another user? Do 'ipcs -m' to list the shared memory segments, the permissions will be listed as per files. Also don't forget that there are two different methods for inreasing shared memory space, a temporay one for the current run and a permanent one for after a reboot. Make sure you have done both.
