Hello,
the output below indicates the memory allocated in the individual functions. So it seems that the mem_copy_subs_noc() function allocates a lot of memory. It is increasing over time? The final output looks like a wrapping error, the counter goes negative.
Which version of Kamailio do you use on the server?
Cheers,
Henning

Hi,
I am suspecitng presence module might be having a memory leak on a production server used by an end user (not have access to it).
The output of command kamcmd mod.stats presence shm is Module: presence { mem_copy_subs(148): 25720 mem_copy_subs_noc(214): 1672201904 mem_copy_subs_noc(251): 678406560 add_event(181): 88 shm_copy_event(57): 40 shm_copy_event(50): 312 add_event(156): 40 add_event(149): 456 new_shtable(66): 5767168 new_shtable(53): 262144 init_evlist(289): 16 Total: -1938302848 }
I am not sure what mem_copy_subs_noc is meaning. And final output is negative, SHM is incfreasing all the time but not sure of the root cause
is this a reasonable hint that a memory leak is related to presence?
