[Freeswitch-users] enable-100rel question

[Steven Ayre]

There's various ways you can help...

If you can test the feature and still get it to crash that helps (it shows
us there is indeed still a problem).

If you can identify an easy way to reproduce it, that helps (it provides a
testcase).

If you can identify what part if the code is crashing (logs & backtrace)
that helps (we can see where the bug lies).

If you can spot the problem in the code and perhaps even contribute a patch
that'd be enormously helpful

This appears to be the latest Jira bug ticket. From the last comment there
it looks like the issue lies within the Sofia-SIP library. We could patch
it and push a fix upstream, or perhaps this has already been corrected
since the ticket is over 4 years old.

I guess the main reason no-one knows is that with that warning no-one has
dared to test it on a production server. :)
