this kind of crash has occurred a few times now with kamailio 4.0:

would be nice to get it fixed.

Hello,
can you give also the output for 'bt full'? Is it latest from branch 4.0 or what specific 4.0.x is?
Cheers, Daniel

One more thing, give also the output for:
p *ptr
in frame 0, if not printed by the bt full.

So the pointer is invalid. That is probably one of the ->next fields in usrloc records list.
Can you go to frame 1 and print ptr there:
frame 1 p *ptr
The interesting file should be the ptr->next.
If it is not 0x696c2f36, then print *ptr->next, then *ptr->next->next until it gets the ->next value 0x696c2f36. I wonder if there are other invalid values on the ptr, or just ->next.
Cheers, Daniel

As this is happening at shut down, does usrloc have a lot of records? Is it taking long to shut down? There is a force killing interval for long shut downs.
