[OpenSIPS-Users] Possible dialog/topology hiding bug

[Bogdan-Andrei Iancu]

Hi Pete,

By doing kill -9, you completely kill ALL opensips processes, so there 
is no cleanup/flush during shutdown. On crashes, the worker processes 
crashes - the attendant cannot crash (as it is not doing anything), so 
this process can do the shutdown in a proper way.

Can you try to see if the call is properly recover if you do normal 
restart (no SIGKILL, but SIGTERM) ? If it does, please take a snapshot 
of the db entry (for that call) while opensips is down - one for KILL, 
one for TERM; and let's see the differences - maybe some dialog data 
gets flushed only during shutdown.
