How to resolve the "No such channel"

We are using Asterisk Occasionally the following returns “No Such channel” error:

MonitorAction monitorAction = new MonitorAction(channel, fileName);
ManagerResponse startRecordResponse = managerConnection.sendAction(monitorAction);

We cannot find and error log in AST log file.

I want to know what could have caused AST return this error and how to resolved it.

Asterisk 1.8 is past end of life.

Your program isn’t in any of built-in languages provided by Asterisk.

If this is AMI, it is normal for calls to go away, or transfer to other channels whilst scripts are running. The only way of stopping it is to give both parties strict instructions not to touch their phones.
