Personally, I have not had any issues. My setup is with PostgreSQL 8.4 and lately PostgreSQL 9.0, and involves use of 'permissions', a few other minor DB-backed modules, and also very heavy use of sqlops. Some of these are very high-volume / concurrent call dense.

How many threads do you have running?
And do you have the permissions module setup as cached or not?

I found that the cause is not in the permission module, but the permissions module (without caching), together with "childeren = 32",
does help to get the problem happen more often.

I have now about 100 threads when kamailio is running ( with childeren = 32 ) on a server with two quad-core processors (8 cores total).
