Hi @arnaud-lb ! I'm trying to handle errors for a producer, and i'm having some trouble. When all brokers are down, the produce() function returns success, but rdkafka internally seems to be indefinitely retrying. I tried catching an exception, but nothing is catched, and adding an error callback, but it segfaults when called (in zend_call_function it seems). Do you have any tips on how to handle a simple synchronous producer such as this ?
