Hi,

I have looked into the problem that you reported, but it does not crash
for me. I have followed exactly the steps that you described. Everything
works as expected and opensips does not crash. I will try to do more tests
maybe it does not appear the first time but will appear later.

regards,
Anca

Message:
Sorry, the scenario is the following (two crashes confirmed):

- alice allows bob in pres-rules.
 - bob subscribes to alice and receives NOTIFY "active".
 - "active_watches" and "watchers" contain an entry with status = 1.
 - alice removes bob from pres-rules document.
- OpenSIPS sends NOTIFY "terminated;deactivated".
- bob subscribes again and OpenSIPS replies NOTIFY "pending".
 - "active_watches" and "watchers" contain an entry with status = 2.
- alice allows bob again in pres-rules.
 - OpenSIPS crashes.
