Asterisk 11.11.0 on CentOS 6.5, installed from RPMs. OpenSIPS fronting
Asterisk from a Tekelec T9000.

I'm accumulating stuck channels.

I'm googling now and I recognize that Friday afternoons are the worst time
to ask questions, but I'm getting desperate because this is keeping me
from rolling a system out to production. (Yup, I know. Who rolls out a
system on a Friday afternoon...)

They all show (core show channels) that they are running one of my AGIs,
so I suspect something changed in processing AGIs from 1.2(!). (I've
recently changed from using 'signal()' to using 'sigaction()' if that
rings any bells with anyone.)

That's puzzling enough, but killing the AGI process from the shell doesn't
help.

Neither does 'channel request hangup SIP/a.b.c.d-00000031'

Neither does 'channel redirect SIP/a.b.c.d-00000031 default,s,3' where
'default,s,3' is a hangup().

Neither of these commands log any errors.

The only other clue may be this message:

Autodestruct on dialog '1405009120-21730426@T9000' with owner
SIP/a.d.b.c-00000031 in place (Method: BYE). Rescheduling destruction for
10000 ms

for each of the hung channels every 30 seconds or so.

I haven't identified what callers are doing to reproduce the error
reliably yet.

Any clues or suggestions?

You might see if they are getting stuck due to a deadlock:

https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace?src=search#GettingaBacktrace-GettingInformationForADeadlock

If you get the traces required, you could open an issue on the bug tracker.

If commands like "core show channel <channel>" and "sip show channel
<channel>" work then you'll want to attach that data as well.
