I've had a problem last night where Freeswitch core dumped complaining about a potential double free. At that time, it was doing an all night automated test batch
with a load averaging 230 simultaneous SIP channels.

If nobody has seen this yet, I'll file a jira about that.

Here is the bt of the dump :
