Shuo Zhang updated KAFKA-9704:
------------------------------
Description:
z/OS won't let us resize file when mmap, so we need to force unman like Windows.
It was found that if messages were ever published to the Kafka server, the
Kafka server will not restart. The issue occurs repeatedly in two of our guest
z/OS systems.
