I've seen it a few times in production already and it filled the disk. You should be able to reproduce it by killing an active RTP stream. I have been using freeswitch, but I don't imagine it is limited to this SIP server. It looks like sofia-sip is driven to continue to receiving media and gets nothing back while the call should be terminated.

Can you reliable reproduce it? It seems sofia-sip is struggling with some input to it and goes crazy after that. I lack a stable way to reproduce it. The lack of \n in that message is annoying too. :(
