I running 1.12.3work4 and I am seeing an occasional memory leak during
bulk calling tests.
I assume the path to reproduce this requires some kind of error, but i
have not isolated that yet.
The backtrace to all the leaked memory comes from
nua_session_usage_shutdown().
I think this happens when the application calls nua_handle_destroy() for
a handle that is in a dialog.
Here is the backtrace for the first item allocated in this path:
su_home_new()+0x5c
msg_create()+0x2c
nta_msg_create()+0x44
nua_creq_msg()+0x1f8
nua_session_usage_shutdown()+352
nua_dialog_usage_refresh()+0x64
nh_call_pending()+128
nua_stack_destroy_handle()+0x28
nua_stack_signal()+0x40c
su_port_getmsgs()+0xb0
su_port_query()+180
su_root_step()+0x28
All the rest of the items allocated are below nua_creq_msg() or
nta_outgoing_mcreate() in the call to nua_session_usage_shutdown().
I am guessing the leak is caused by:
nua_session.c line 1175:
if (cr->cr_orq) /* Wait for BYE to complete? */
nua_creq_deinit(cr, NULL);
So we don't deinit here. But, the handle does get freed.
I'll try to get a SIP trace that causes this, but it may not be easy.
Any thoughts ?
Think we should fix this for 1.12.4 ?
