在我们的 kafka 集群中，broker 的内存使用量不断增加。
简单的 lsof 调查显示许多具有相同 pid 但不同用户打开相同文件并持有内存的 opefile
root@kafka-0:/# lsof /data/topic-x/00000000000000000000.log
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 10 root 333u REG 253,3 36407956 3669557 /data/topic-x/00000000000000000000.log

我可以看到同一进程的多个线程。分配给每个线程的堆内存最小为 1gb，最大为 4gb，为什么每个线程都分配了堆内存，这不应该是所有线程堆内存的总和。总线程内存不应超过 4GB
