Red Hat Issue Tracker ISPN-1869 0 Major Resolved EvictionConfigurationBuilder.validate() should warn if user setd a maxEntry but forgot strategy 2014-03-31 12:05:40 UTC

Description Michal Linhard 2012-02-24 17:45:28 UTC 
eviction is set to limit data load to 10000 entries, even though it isn't configured.

see http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-QE/job/edg-60-experiments-mlinhard/210/
Comment 1 Michal Linhard 2012-02-25 20:25:01 UTC 
Seems like this default is being honored:
https://github.com/jbossas/jboss-as/blame/master/clustering/infinispan/src/main/resources/infinispan-defaults.xml

I wonder why this hasn't been a problem before ... it's been there for a while...
Comment 2 Tristan Tarrant 2012-02-27 09:40:05 UTC 
This is caused by bad interaction between ISPN-1869 and AS7's defaults.
Comment 3 Tristan Tarrant 2012-02-27 10:32:34 UTC 
Workaround: add <eviction strategy="NONE" maxEntries="0" /> to work around this issue
Comment 4 Tristan Tarrant 2012-03-01 14:18:30 UTC 
As soon as we get an EAP build based on 7.1.1 which will pull in Infinispan 5.1.2 this should be fixed
Comment 5 Ondrej Nevelik 2012-03-29 19:06:57 UTC 
Fixed. Verified by removing <eviction-strategy=NONE max-entries=0/> from our configs and running a test, no entries are evicted, see chart - https://bugzilla.redhat.com/show_bug.cgi?id=797265
