Describe the traffic that generated the bug We tried to upgrade from version 2.4 to 3.4. It's a two nodes cluster with anycast setup. When more and more calls hits opensips, it keeps crashing.

Hi @williamjing1984 , the links do not have the right permissions to be accessed by anyone :( . Also be sure you post only the backtrace, not the actual core file.

Hi

I have updated the link.

Please check again. Thanks.

Both backtraces show a crash while trying to do tracing for what seems to be a re-INVITE.

When and how do you trigger tracing in your script ?

[williamjing1984]

modparam("tracer", "trace_id", "[tid]uri=hep:hep_dst") modparam("proto_hep", "hep_id", "[hep_dst] production-hep-server-url:port-number;transport=udp;version=3")

then basically use below when we want to send the dialog or transaction to our homer7 back-end server in the opensips.cfg trace("tid", "d","sip|xlog" ,""); trace("tid", "t","sip|xlog" ,"");

We did notice there are some warning logs like WARNING:tracer:trace_w: can't trace dialog! Will try to trace transaction

Does it mean we need to use trace("tid", "t","sip|xlog" ,""); instead of "d" for the places where dialog is not available?

And Is below the only change from version 2.4 to 3.4 re the sip_trace module? Because it works in version 2.4. https://www.opensips.org/Documentation/Migration-2-4-0-to-3-0-0#toc23
