[rabbitmq-discuss] Can't process_flag(trap_exit, true) in process

[Alexandru Scvorţov]

Hi David,

> I create a connection and channel in process 1, and subscribe a queue with process 2, which created by "spawn_link" in process 1, if I run "process_flag(trap_exit, true)" in process 1, the process 2 will receive a 'basic.cancel' message for the subscribe queue. If I don't run "process_flag(trap_exit, true)" in process 1,  the process 2 will never receive that.

I don't follow.  Are you saying that running "process_flag(trap_exit,
true)" in process 1, the queue will get deleted immediately (and hence
process 2 will receive a basic.cancel)?

Could you post your code please?

Cheers,
Alex
