[asterisk-users] Need help troubleshooting Asterisk Auto dial out problem

[Jesse Thompson]

We've built an alert system at our company so that if our monitoring
software notices anything very bad happening, and we don't react to a text
message after a few minutes, then it will begin to call our telephones
directly. This seems to help a lot with staff who are asleep, or who might
not be near enough to the phone to hear text message notifications.

We do this by having a folder full of .call files, and programatically
moving a copy of the appropriate call file
into /var/spool/asterisk/outgoing/ when an outbound shout is required.

This has worked well for a couple of years, but recently we are
experiencing a problem where sometimes Asterisk will simply ignore this
folder. When we notice the logjam of ignored call files
in /var/spool/asterisk/outgoing/, then we restart the asterisk daemon and
things run smoothly again.

When "wedged", the Asterisk daemon will function normally in every other
way that we use it. The PBX still functions, outbound manual calls still
function, inbound calls, voicemail, nothing else appears to be negatively
impacted. However new files introduced into /var/spool/asterisk/outgoing/
folder get ignored. No messages spring up on asterisk -rvv console, nothing
shows up in the logs, the .call files just get snubbed. We're at a loss to
determine what other debugging avenues may be available, and we have
googled for every applicable keyword we can think of including "asterisk
auto dial" and "pbx_spool" to no avail.

We are running:
Asterisk 1.8.13.1~dfsg1-3+deb7u3 built by pbuilder @ pungenday on a x86_64
running Linux on 2014-01-04 01:03:48 UTC
on Debian Linux stable (wheezy). It is possible that this symptom began a
few months ago after a system update (apt-get update; apt-get upgrade).

Any advise to further track down what is going on would be appreciated,
thank you!
