[Asterisk-Dev] Asterisk server hangs

[Luis Mata]

I have a thought.

    This never happen to me under redhat 7.3 but I just happen to checkout
from cvs under Redhat 9 and now it's happening to me. So, I think is a
version related issue with Redhat 9. Unless it's is also happening on Redhat
7.3 ???

I've been trying to find people with this sort of problem.  Can you
confirm that the leak are extra sip channels by doing "sip show channels"
when it is going on?  Also remember you'll have to type it at the real
console or alternatively have an asterisk -r always connected.  Find me on
IRC to discuss further.
