</div>These look a lot like the "Zombie Channel Bloating Death" problems<br>
we attacked over the last few weeks. Please see if the latest svn<br>
version<br>
of 1.4 has these problems still. In high-volume systems, this looked<br>
like<br>
a huge memory leak that would lead to death by swiftly using up memory,<br>
file descriptors, etc. until Asterisk ran out of virtual memory and<br>
crashed.<br>
<br>
There are a couple of code paths, one leaves CANCELED channels lying<br>
around, the other BYE'd channels.<br>
