Squid diskd msgget error in jail

[Johan Hendriks]

Hello i have installed FreeBSD 6.1 with jail created with ezjail

One jail i want to use as a squid proxy
I installed squid 2.6.3 and al works fine except for the diskd cache.
This is what i get from the jail /var/log/maillog 

Oct 16 12:26:54 proxyserver (squid): msgget failed
Oct 16 12:26:54 proxyserver squid[98292]: Squid Parent: child process 98317 exit

If i install squid on the jailhost itself it all works as expaected and the diskd service starts withou a problem.

Do i mis something from the jail.
