Hi Ben,

Do you have a full backtrace extracted from the core ?

In regards to the TCP processes, the TCP layer will automatically enabled itself depending on what protocols (tcp-based) you are using in script. Maybe you do not use SIP with TCP, but do you use BIN or HEP ?

Hi,

I am currently upgrading to 2.3.3 and am running off the HEAD of the 2.3 branch. My OpenSIPS is consistently crashing when trying to process the ACK to an initial INVITE request. I am testing with SIPp using a simple single call scenario. I see the following in the logs:

I also notice that OpenSIPS is starting up a number of TCP processes even though I do not use TCP in my script. I do not even have the proto_tcp module loaded. I used to use the “disable_tcp” global parameter in 1.11, but that has been removed in 2.3.

I also have the core dump if any more information is needed from that.

Thanks,
