Description
the drillbit down for every 7 or 8 day. i print the gc details and find a lot of full gc before down. I dump the heap and analysis with mat and find the ListenerPool may have problem.
Below is the full message in mat leak suspects:
One instance of "org.apache.drill.exec.rpc.bit.ListenerPool" loaded by "sun.misc.Launcher$AppClassLoader @ 0x638052d50" occupies 3,484,931,208 (98.72%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentHashMap$Segment[]" loaded by "<system class loader>".
Keywords
java.util.concurrent.ConcurrentHashMap$Segment[]
org.apache.drill.exec.rpc.bit.ListenerPool
sun.misc.Launcher$AppClassLoader @ 0x638052d50
Then i quick look at ListenerPool and does not find any place to remove object from the listeners. Does this is a problem?
