----------------------------------------
Summary: Cache close with partitioned regions does not close all
the region's statistics
Key: GEODE-10328
URL: https://issues.apache.org/jira/browse/GEODE-10328
Project: Geode
Issue Type: Bug
Components: core
Reporter: Darrel Schneider
I noticed when looking at hprof memory dumps of a JVM whose cache had been
closed that something was keeping the PartitionedRegion instances from being
garbage collected. It turns out that the region's RegionPerfStats instance was
not closed. Other stats for the region were closed but not the one owned by
PartitionedRegionDataStore's bucketStats instance variable. This indicates
that the PartitionedRegionDataStore.cleanUp method is not being called.
It looks like the bug is in: PartitionedRegion.postDestroyRegion. It has a code
path that handles Operation.CACHE_CLOSE and Operation.FORCED_DISCONNECT without
calling "closePartitionedRegion" which invokes "dataStore.cleanup".
This buggy code path has its reasons for not calling closePartitionedRegion. To
fix this bug it would be easy and safe to have this code path call
dataStore.getCachePerfStats().close()
