Summary: org.apache.drill.exec.rpc.bit.ListenerPool leak suspects
Key: DRILL-785
URL: https://issues.apache.org/jira/browse/DRILL-785
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Affects Versions: 1.0.0-milestone-1
Reporter: griffin li
Priority: Critical
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？
