Using registered() in event_route[usrloc:contact-expired] causes Kamailio to hang

[oej]

In the contact-expired event route I want to check if the expired AOR is registered elsewhere, by checking replicated location tables like "location-peer". Using the registered("location-peer", "") function causes Kamailio to go to sleep and not respond to rpc commands.

What is the db_mode you tried with?

No DB at all

Using another function that tries to access the same location record that expired is trying to lock same slot in usrloc internal hash table. The solution would be implementing re-entrant locks there. I will try to do it when I get the first chance.

I pushed a commit to master to make the locks in usrloc reentrant. No testing for reported case, would be appreciated if you can give it a try.

The changes are to a critical module, so we may need to live with this limitation until 5.0.
