Hello,
I'm trying to replicate a hash table to another 2 nodes by using DMQ
Module. That's the related configuration:
loadmodule "tm.so"
loadmodule "tmx.so"
loadmodule "dialog.so"
loadmodule "dmq.so"
loadmodule "htable.so"
modparam("dmq", "server_address", "sip:MY_INTERNAL_IP_ADDR:5062")
modparam("dmq", "notification_address", "sip:dmq.domain.local:5062")
modparam("dmq", "multi_notify", 1)
modparam("dmq", "num_workers", 4)
modparam("dmq", "ping_interval", 90)
modparam("htable", "enable_dmq", 1)
modparam("htable", "dmq_init_sync", 1)
modparam("htable", "htable", "test=>size=10;initval=0;dmqreplicate=1;")
if(is_method("KDMQ")) {
dmq_handle_message();
exit;
}
After starting Kamailio - everything seems to be working fine, Kamailio is
able to discover other nodes and replications is working fine, until after
a few minutes I'm getting such errors in the Kamailio Log file:
May 8 17:14:26 kamailio kamailio[28064]: CRITICAL: <core>

Then, if I'm getting any SIP messages from any Device - Kamailio is
crashing with the following info in the log file:

By disabling DMQ Module i haven't noticed any crashes or issues like that,
so i suppose that Kamailio is crashing because of this module, but i can be
wrong. I've tried with 2 versions of Kamailio (5.2.6 and 5.3.4), both of
them having the same issue.
Thanks
