Thanks Daniel, What is a typical configuration for 1000 and 10000 connections?

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

Hello,

looks like you haven't reserved enough shared memory for the load you want to handle. Increase it via -m command line parameter, by default is 32MB which is quite low for stress testing.

Cheers,
Daniel

I have never seen this before...

what could cause this? Is there something I could do to fix this issue?
