Do you know if garbage collections are happening? Try running with the -verbose:gc option. It could be that the objects ARE being dereferenced, but just aren't being collected before your loop ends.

The following is a snippet of my code and config file: for(int i=0; i < 200000000; i++) { Vector vec = new Vector(); testCache.put("testkey"+i, vec); } # DEFAULT CACHE REGION (memory cache) jcs.default=DC jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes jcs.default.cacheattributes.MaxObjects=2000 jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru .LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=true jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.elementattributes=org.apache.jcs.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.MaxLifeSeconds=43200 jcs.default.elementattributes.IsSpool=true jcs.default.elementattributes.IsRemote=false jcs.default.elementattributes.IsLateral=false #Auxiliary CACHE (disk cache) jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheFacto ry jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.IndexedDis kCacheAttributes jcs.auxiliary.DC.attributes.DiskPath=jcscache jcs.region.testCache=DC jcs.region.testCache.cacheattributes=org.apache.jcs.engine.CompositeCacheAtt ributes jcs.region.testCache.cacheattributes.MaxObjects=50 jcs.region.testCache.cacheattributes.MemoryCacheName=org.apache.jcs.engine.m emory.lru.LRUMemoryCache jcs.region.testCache.cacheattributes.UseMemoryShrinker=true jcs.region.testCache.cacheattributes.ShrinkerIntervalSeconds=60 jcs.region.testCache.elementattributes=org.apache.jcs.engine.ElementAttribut es jcs.region.testCache.elementattributes.IsEternal=false jcs.region.testCache.elementattributes.MaxLifeSeconds=43200 jcs.region.testCache.elementattributes.IdleTime=43200 jcs.region.testCache.elementattributes.IsSpool=true jcs.region.testCache.elementattributes.IsRemote=false jcs.region.testCache.elementattributes.IsLateral=false When I run this code the memory on my system goes down very quickly. I expected that after the first 50 elements it would start putting items on disk and removing them from memory but this does not seem to be happening. I see the file on disk getting increasingly bigger but memory still keeps going, leading me to believe that the elements are not getting garbage collected or was never freed. Am I doing something incorrectly? Thanks, Daniel __________________________________ Do you Yahoo!? Yahoo!
