shmget() failed: Function not implemented

[duzap]

I am using FreeBSD 7.1 and I am receving the following error in many places:
shmget() failed: Function not implemented
Failed to start up concurrent users module!

for example:

# ./build update_versions
shmget() failed: Function not implemented
Failed to start up concurrent users module!
shmget() failed: Function not implemented
Failed to start up concurrent users module!


another example:

# php -v
shmget() failed: Function not implemented
Failed to start up concurrent users module!

what could be the problem and how can I solve it?

p.s: my apache error log is also full with this error message.

I have never seen this message, are you using a GENERIC kernel or did you make a custom one? The latter might be the problem in that case.

My machine works fine with this uname -a output...

FreeBSD xxxx 7.1-STABLE FreeBSD 7.1-STABLE #4 r186904: Thu Jan 8 19:11:44 CET 2009 root@xxxx:/usr/obj/usr/src/sys/XXXX i386

(The r number comes via SVN, I host a local copy, you are not expected to have that value as well :))

Do you use FreeBSD jail? If so try to set security.jail.sysvipc_allowed to 1 on root machine.

You removed SVSv IPC from your kernel. You need to enable it again

Have you compiled a custom kernel? That could be the reason...:) (http://phone-central.com/)
