Summary:                    IAX2 crashes with many leftover threads.
Description: 
After installation of Asterisk 1.4.21 on two nodes, one in Europe and one
in the US we did get problems related to the IAX2 protocol.

The IAX2 protocol was set up to be used as a trunk as the config in the
additional information. The config is set up symmetrically on both sides.

What happens is that a call can be established, but after a while (usually
a minute) the line goes silent and the command "iax2 show threads" lists
more than 100 threads instead of the usual 10. After the call has been
crashed it's no longer possible to establish a new call.

Asterisk doesn't respond to the "stop now" command either, so the only way
to resolve the problem is to do a 'kill -9' on the asterisk process and
restart it.

The problem has occurred on both nodes, but it seems to be the called node
that's most likely to crash. However the calling node can also crash.

The problem has occurred regardless of if the phones connected were SIP
phones or ZAP phones, so this has led me to strongly suspect the IAX2
protocol.

Reverting to Asterisk 1.4.20 resolved the problem.
