--------------------------------
Summary: Replace with concurrent clear and destroy leaks off heap
memory
Key: GEODE-5292
URL: https://issues.apache.org/jira/browse/GEODE-5292
Project: Geode
Issue Type: Bug
Components: regions
Reporter: Dan Smith
For a region that has been configured with off-heap storage and overflow to
disk, memory can be leaked if
* region clear
* region destroy
* region replace
all happen concurrently. The root cause appears to be region clear modifying
entries for values stored on disk without synchronizing the entries. This
prevents replace from freeing the off-heap memory for the new value when the
replace fails because the region is being destroyed.
