Hi, we're using Asterisk 1.6.1.1. We've got a memory leak with unconnected static users. Our template for static users in users.conf is: [static](!) hassip=yes hasiax=no type=friend [100](static) context=periferico host=192.168.0.1 port=5060 username=100 [101](static) context=periferico host=192.168.0.2 port=5060 username=101 ...... This template generates polling with SIP OPTIONS messages to static users. We don't generate call then these messages are the only object created more than once (i think..). If users aren't connected we have a memory leak: the memory used by Asterisk grow up and generate (after a time that depends from the number of static users) an OOM and his consequent kill. Using refcounter debug (uncomment REF_DEBUG macro in chan_sip.c), we noticed only peer objects (builded by build_peer) have "Refcount not zero". Reading /tmp/refs, we noticed destructor is called for all channels created (with sip_alloc) for to send SIP OPTIONS message. This channels appear into refcounter debug when message is sent, but not when timout expires and they are destroyed with **call destructor**. Using our users.conf, the same thing happens with version 1.6.1.6, but not with 1.4.22. Do you have any suggestions? Thanks a lot.
