After some deeper dive, it seems that the problem is with HashMap usage in
EventQueueBackingStoreFile.
Almost every time I run jstack the JVM is inside
EventQueueBackingStoreFile.get() doing either HashMap.containsKey() or
Integer.valueOf().
This is because of overwriteMap is defined as regular
For example this stack trace:
lifecycleSupervisor-1-2 prio=10 tid=0x7f89141d8800 nid=0x5ac8
runnable [0x7f89501ad000]
java.lang.Thread.State: RUNNABLE
at java.lang.Integer.valueOf(Integer.java:642)
at
That is actually a symptom of the real problem. The real problem is that the
remove method ends up hitting the main checkpoint data structure and causes too
many ops on the hash map. The real fix is in the patch I mentioned which reduce
the number of ops tremendously.
