The crash happened during a shutdown. Is this shutdown the result of a normal opensips termination, or it is a result of opensips crash ?

[46labs]

crash

[bogdan-iancu]

In this case I will discard this report - the shutdown after a crash degenerates in 90% in a second crash (of the attendant process which does the shutdown) as data is already corrupted in mem (due the original crash).
If there are crashes during normal shutdown, please open a new issue.
