Yes, the program is stuck in the `create_producer` call. There are no log lines indicating "Unable to create Producer"; I believe it is either getting stuck before that or not flushing its output (while I'm running with PYTHONUNBUFFERED=1, that may not apply to whatever autoflush behavior is configured inside the C++ code). The fact that the producers become unstuck when the brokers are unpaused (unstopped) also indicates that there may be a missing connect timeout. Attached is an entire unedited log segment recorded during the SIGSTOP of a single broker. These logs were generated in a foreground PTY (no kubernetes swallowing/buffering output). The code used is exactly the code copied above with no changes. The logs below showed no activity for more than 5 minutes. In this log segment, the broker was killed at 15:48:46 [logs_f.txt](https://github.com/apache/pulsar/files/6577581/logs_f.txt) -- This is an automated message from the Apache Git Service.
