[asterisk-users] channel.c: Unable to request channel ZAP

[Asterisk]

Zap show channels shows only 2 or 3 channels to be in use ... others are
not. Resetinterval is set to 1200 (20 minutes).

What does "zap show channels" show?  Are all the channels shown as in
use? What is set in zapata.conf for resetinterval= ? If anything.  I
believe that resetinterval is used to reset unused channels for any
channels that are left open.
