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;```
