Hi Stefan,
The fix must be applied in addition of the growth of SHM?
What exactly the fix will avoid?
Regards,
Igor.

Hi Igor,
Yes, it's caused by lack of shm.
I don't know if there is a proper shm value. Depending on how many modules are loaded \
on kamailio and how much shm a module might use over time, more or less shm should be \
used. In your particular case, depending on how much userblacklist table should grow, \
you should adjust the startup shm value.
Thank you for your detailed feedback on the segfault; the fix it's on its way and \
will be backported.
Stefan

Hi Stefan,
Indeed, It looks to be the issue.
But, the root cause is the lack of SHM memory, isn't it?
Actually, Kamailio is running with 256M of SHM (-m 256). What would be the good new \
value?
Regards,
Igor.

I remember something related, solved and backported in commit [1].
Now that I'm looking at the segfault line I think node should be NULL checked also \
after ```struct dtrie_node_t *node = root;```
