It depends of what is associated with a connection, if there is a 
registration, then also the usrloc record has to be taken in account.

The best is that you start is and open like 1000 connections. use 
kamctl/sercmd to dump shared memory usage. The add another 1000 and see 
the difference of the used memory.

Then you have to take in consideration extra events, such as calls that 
can use shared memory for transaction management.

On current OSes, kamailio does not block the memory allocated for it. It 
is virtual memory that is given on demand. It is more like upper limit 
for safety reasons, in case there is a leak, kamailio stops asking for 
more memory, therefore it does not block other apps. So you can give to 
'-m' parameter values such as few gigas.

Cheers,
Daniel
