[SR-Users] Question about debugging using `kamcmd pkg.stats`

[Lucian Balaceanu]

Hi Daniel,

Thank you for yesterday's input.

By doing some debugging on the 'no private memory left' I came to the 
conclusion that there is enough private memory as a whole to allocate 
the required amount, but that there is no single free chunk big enough 
to accommodate the required size.
This is a valid scenario when MEM_JOIN_FREE is 0, right?

Btw, how can I determine if I have this MEM_JOIN_FREE set or not? I am 
looking in `kamailio -V ` output and in the kamailio.cfg and mem_join is 
not set. I cannot determine in which version MEM_JOIN_FREE is supposed 
to be set by default - how can I find this?

Thank you,
Lucian
