timer_mutex not destroyed in pjsua_core.c

[mlistsdm@xxxxxxxxx (Dmitry M)]

After calling:

status = pjsua_create();
....
pjsua_destroy();

several times in a row, pjsua_create() started to return error:

21:50:03.003   pjsua_core.c  Unable to create mutex: Resource busy 
[status=120016]

It seems it happen because one of the mutexes was not destroyed. 
Applying the patch as bellow fix the issue.



After resolving the first issue I've got similar case in 
sip_transport.c. At some point this code returns status: "Resource busy".

     status = pj_lock_create_recursive_mutex(pool, "tmgr%p", &mgr->lock);
     if (status != PJ_SUCCESS)
         return status;

It looks like in some cases this mutex wasn't destroyed. It's not so 
obvious where. Please advise what can be wrong.


Thanks,
Dmitry
