[Freeswitch-users] Subscribing to events in managed C# / .NET

[Josh Rivers]

It does from a fresh start of FreeSWITCH. I've noticed, although not really
confirmed, a race condition between the unload and reload of managed code.
It seems that threads started in the newly submodule are terminated along
with the threads for the old, unloading submodule. Is that what you are
seeing as well?
