Is there a limit to the number of users which can be registered on Kamailio at any one time, or a configuration file which sets this.

I have just installed Kamailio in a lab environment for testing purposes but I seem to only be able to register 1024 users, all remaining Register requests are ignored.

I am not using a database to authenticate users or anything, just want to be able to register upto 10,000 users.
