[rabbitmq-discuss] After weekly log rotatation was done, the command "rabbitmqctl rotate-logs" never stop

[Nate]

Hi Matthias,

    Bad news, I cannot get the dump file via command "kill -SIGUSR1 8972"
and process still exist. Are there any other method to get the dump file?
Btw, this is first time the rabbitmq-server did the log rotation.
Thanks a lot.

Best Regards,
Nate
