Philippe Mouawad updated OFBIZ-4220:
------------------------------------
Priority: Critical (was: Major)
Description:
If maxInMemory is set on caches, then current implementation will leak if many
puts are done in cache.
We made some load testing and current implementation ends very rapidly in an
OutOfMemory.

Hello,
Since some time UtilCache has been updated to replace the WeakHashMap by a
ConcurrentHashMap:
private static final ConcurrentHashMap<String, UtilCache<?, ?>>
utilCacheTable = new ConcurrentHashMap<String, UtilCache<?, ?>>();
I think this fix to concurrency issues has introduced a memory leak or at least
a much bigger impact on Memory.
Indeed descendent of AbstractCache (particularly AbstractEntityConditionCache,
EntityListCache) tend to create many caches that do not need to always persist
in time.
The old WeakHashMap handled this by enabling them to disappear while today the
Hard ref disables this.
We made some load testing and current implementation ends with an OutOfMemory.
Summary: Current implementation of UtilCache has a memory leak if
maxInMemory is set (was: Current implementation of UtilCache has a memory leak)
> Current implementation of UtilCache has a memory leak if maxInMemory is set
