   Finally, I resolve this problem.
   Every time load test will repeat this scenario. but this time, the error throws #IOException: Map failed#, and the logs shows broker mapped lots of file, I guess there is some relationship.
   After tuning linux param: sysctl -w vm.max_map_count=655360, the problem solved.
   Actually, this crash caused by ourself, because rocketmq has a tuning bash, we forget running.
