@tejas3190 Why did you close this issue?

[tejas3190]

Well i just thought the implementation that i was trying was wrong. I had a signal handler in which i tried to close the consumer connection which is leading to crash. Any call to consumer api (in confluent - python) leads to crash when called from signal handler.

[edenhill]

Okay, yeah, that makes sense. Signal handlers are inherently unsafe on Unix
