[SR-Users] Problem implementing usrloc via dmq

[Aleksandar Sosic]

Hi Charles,

I did solve the problem with

if(is_method("KDMQ")) {
    dmq_handle_message();
}

in the main route and the dmq_usrloc is working now.

I enabled dmq for the dialog also:
modparam("dialog", "enable_dmq", 1)

and the dmq is working between kamailio instances but the call does
not end and the kamailio instance where the call was made crashes.

sr01.evox.it    | 30(38) CRITICAL: <core> [core/pass_fd.c:277]:

I have also done a gdb on the core dump:

But cannot manage to solve the issue now.

NB. I have this order of modules loades:
...
loadmodule "dmq.so"
loadmodule "dmq_usrloc.so"

loadmodule "htable.so"

loadmodule "dialog.so"
...

# ----- dialog params -----
# modparam("dialog", "db_url", DBURL)
modparam("dialog", "default_timeout", 10800)
modparam("dialog", "profiles_with_value", "calllimit")
modparam("dialog", "enable_stats", 1)
modparam("dialog", "db_mode", 0)
modparam("dialog", "dlg_flag", FLT_DLG)
modparam("dialog", "enable_dmq", 1)
...


Do you have any hints?

Thanks in advance,
