it crash.

Hi Richard, Alex,
I'm curious about it. Is there a way of simulating this? Under what
conditions should this happen?
The first case described (differing number of ports) I'm not 100% sure
about. I'm thinking the little used slash notation in the SDP m= line might
be to blame... one side using it (say, 1234/2 to advertise 4 ports being
used), the other side not using it. You'd end up with 4 ports open for each
side, but some of them unused. And then UDP packets coming in on those
ports.
The race condition is harder to test. You'd have to predict which ports
will be opened when an "offer" is received, and have these ports hammered
with UDP packets ahead of time, while the "offer" is being processed.
cheers
