So I was kind of wrong here. Kamailio runs ok with memory-only presence as long as there are only a handful of subscriptions happening. I noticed that running memory-only presence with `modparam("presence", "enable_dmq", 0)` kamailio will not complain about the originally posted issue but will still crash with this kernel error in the logs: ``` kamailio[13043]: segfault at 0 ip 00007f9f75d624d7 sp 00007ffd11cf7ee0 error 4 in presence.so[7f9f75d53000+fe000] ```
Do you still need a coredump to go further or is this enough info?
