[Kamailio-Users] Perl module and memory leak in append_branch

[Daniel-Constantin Mierla]

 From the log I see that at shutdown, only pkg allocated at startup is 
still allocated (e.g., mk_action is used to create the cfg tree which is 
executed at runtime).

If you can point me exact part of log that intrigues you, I will have a 
look. Other option, if you get out of memory (and not only) from a 
specific pid, send a SIGUSR1 to that pid and you will get the mem status 
-- make that part available somewhere for investigation.

Cheers,
Daniel
