New subject: [kamailio] Possible Kamailio presence server (BLF) memory leak (#155)

11 May 2015


      Hello I have problem with Kamailio presence,dialog(BLF) server, that not released memory.
In product enviroment stop working after cca. week in test enviroment out of memory after cca. 12000 calls.
I create test enviromet on one openvz debian wheezy server where run:
* kamailio stable 4.2.4 (x86_64/linux)  as registrar and main proxy
* kamailio develop 4.3.0-pre1 (x86_64/linux) as presence server
* sipp uas and uac
* connect sip phone grandstream GXP2160 with 24 blf buttons
On grandstream gxp2160, sets programable keys to blf 1-24. 
BLF works correctly, only problem is a memory leak. 
The stable kamailio as presence server leak too.
