             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.
