[sr-dev] Dialog module issues

Hi Kamailians! Benoît and I have discovered multiple issues we think is related to our use of the Dialog module with DMQ replication. We’ve seen enourmous spikes where SHM memory is quickly consumed to the top limit and Kamailio core dump. We see stuff left in databases that should have been deleted and a few other issues. The crashes worries me most. It could be our signalling pattern or something else that leads to a state where we can’t rely on the the “number of active dialogs” stats. If any other developer recognize this, or has recently dived into the deep inner workings of Dialog I’ll be happy to have a brainstorm. If not, I’m going to have to take a deep breath and try to figure it out… :-) At this point we can’t replicate it. We’re going to try hard doing that so that we can assure that any fixes applied will actually work. Regardless if we have some bad routing, nothing should be able to crash a running Kamailio and eat up memory in an uncontrolled way, so there must be a problem in the code somewhere. I’ll start parsing the logs… Cheers, /O
