This would happen if the session somehow got removed from the session
manager before the AMQP channel closure handshake was completed.

What channel number got reported in the error?

[BC]  The channel number was 9 last time. I saw different channel
numbers before. None of them was 0. I think all were positive and less
than 20.

Nope. It could be a bug in the client library.

Have you got a test case that reproduces the problem?

[BC] The problem happened randomly.  But it is not difficult to make it
happen. I just need to run some long jobs.
