Hi Jerry, We have a sofia based UA application that has been running on 1.12.6 for quite a while. The application does call nua_handle_destroy(). It is in the debug print trace after the r_bye event.
I have many tools to watch memory usage, but the easiest way to see this is to look at the VmData in the /proc/pid/status file. I determined it was a handle by using mtrace(). I also have a way to display all the memory allocations by object since sofia has an object based memory allocation scheme. Some interesting details: The handle no longer lives in the nua agent nua_handles list. The handle home object has 1 reference. The handle has a sub object which is also a home, which also has 1 reference. This object was allocated in nua_client_check_restart(), by ca_create(). My guess here is the credentials created for the handle are not being dereferenced. Strange that this only happens when we generate the BYE. If we CANCEL or receive a BYE, the handle is freed.
