3.13.7: consume stopping

[Дмитрий Николаевич]

Rabbitmq v. - 3.13.7
Debian GNU/Linux 11 (bullseye)

Classic Queue v. - 2 

Hello everybody.

After updating to 3.13.7 we have next problem. Our client stops consume data from non empty queue after some time. It's connection is alive, amqp.heartbeat are OK.

ns (netstat) util shows that connection is ESTABLISHED, recv and send buffers are empty.

Unacked volume is 0, not pending packets.    

there are next messages

Is it triggered by this problem: https://github.com/rabbitmq/rabbitmq-server/issues/12367 ?

Hi,

It is hard to say without code to reproduce. The log indicates that the queue process crashed, but did it restart after? Considering upgrading to community supported versions (4.2.x). 

This is not the "pread parse"-suite of bugs linked.
