What do you mean with "crash"? Usually if Kamailio runs out of memory it 
logs error messages but it does not crash.

How do you verify the memory consumption? With top or other tools? If 
the memory consumption reported by the OS is increasing then there is a 
problem with an external library.

Kamailio internally allocates at startup a fixed size of memory which is 
never increased. If system memory consumption is increasing then it is 
by an external library which does not use Kamailio's memory allocator.

So what exactly is happening? Is Kamilio just running out of 
pre-allocated memory or is system-memory increasing? How does it crash 
in detail?
