[asterisk-users] "Expected to acknowledge ticks" problem

[David Cunningham]

Hello,

We are seeing an issue where a call will be "stuck" for roughly a minute or
so and in the Asterisk log give many "Expected to acknowledge ticks"
warnings as below. Can anyone suggest a cause? The system is running
11.21.2.
Thanks in advance.
