the memory existing in the system is not used by kamailio unless you 
specify it. By default kamailio uses up to 32MB of shared memory, when 
that limit is reached, then you get out of shm memory error messages. 
You can increase that by -m parameter. For example, if you want to start 
it with one GB of shared memory, then use: -m 1024

Insufficient memory allocated is one possible case, the other one is a 
memory leak somewhere. Do you have big traffic on the box?

Cheers,
Daniel
