Jonathan Santilli commented on KAFKA-7508:
------------------------------------------
Hello Sathish Yanamala the logs show a clear java.lang.OutOfMemoryError: Java
heap space.
Can you provide pease the whole java command executed to run the Broker?
Also, it is possible that the machine does not have that 10GB you are trying to
claim? how many processes are you running on that machine that could be
consuming resources not enabling the Broker to have enough capacity?
