[jboss-jira] [JBoss JIRA] (WFLY-10649) Eviction doesn't work for infinspan distributed cache "dist"

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-10649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13601667#comment-13601667 ] 

Paul Ferraro commented on WFLY-10649:
-------------------------------------

[~xtron] Perhaps I was unclear.  The distributed session manager does not treat max-active-sessions as a hard limit - but rather the maximum number of sessions that can be active in memory.  Any excess sessions are passivated to disk - which is precisely your use case, AIUI.

Additionally, Infinispan memory size attribute operates per-cache entry, which, while proportional, does not directly translate to the number of sessions.
