There is a cache configuration without any eviction config: The eviction is configured dynamically, and following entries are put into the cache: Key_1=value_1, Key_2=value_2,Key_3=value_3 CacheManager cacheManager = com.bspartners.util.ServiceLocator.getCacheManager(); Cache expirationCache = cacheManager.getCache("prodb-expiration-cache", true); Node rootNode = expirationCache.getRoot(); Fqn cacheFqn = Fqn.fromString("/OTTO"); Region region = expirationCache.getRegion(cacheFqn, true); ExpirationAlgorithmConfig expirationAlgorithmConfig = new ExpirationAlgorithmConfig(); expirationAlgorithmConfig.setExpirationKeyName(ExpirationAlgorithmConfig.EXPIRATION_KEY); EvictionRegionConfig erc = new EvictionRegionConfig(cacheFqn, expirationAlgorithmConfig); region.setEvictionRegionConfig(erc); EvictionConfig evictionConfig = new EvictionConfig(); List should be evicted because value is expired! Object value = rootNode.getChild(cacheFqn).getChild(Fqn.fromElements("key_1)).get("key_1"); After getting the value for key "key_1" after 15 seconds there is the value in the cache. The expiration or the eviction respectively did not start. The RegionManager in JBoss web-console dumps the region. Why is evitionQueueSize 0? Region RegionImpl{fqn=/OTTO; classloader=null; status=ACTIVE; eviction=true; evictionQueueSize=0} Dumping the cache in JBoss web-console lists --- Cache1 --- /  null   /OTTO  null     /key_2  {expiration=1352982716472, key_2=value_2}     /key_0  {expiration=1352982716472, key_0=value_0}     /key_1  {expiration=1352982716472, key_1=value_1} - ----------- -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/776685#776685] Start a new discussion in JBoss Cache at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
