[jboss-jira] [JBoss JIRA] (AS7-4018) Large amount of open files for jsf-impl on AS 7

[Cody Lerum (JIRA)]

    [ https://issues.jboss.org/browse/AS7-4018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679078#comment-12679078 ] 

Cody Lerum commented on AS7-4018:
---------------------------------

by changing my vm options to  

"-XX:+UseConcMarkSweepGC -XX:+ExplicitGCInvokesConcurrent -verbosegc"

The files are now cleaned up much more frequently and I'm never going above 20

I'm thinking with my large heap -Xms3072m -Xmx3072m  + -XX:-DisableExplicitGC + G1GC and a pretty quiet application the vm could avoid doing a gc for days or weeks. Thus these references could just sit without being cleaned up.

I'm guessing there is an underlying problem though with something not closing these streams. All I can find is that these are open streams with references to java.lang.ref.Finalizer

> Basically what I am seeing is the amount of open files for the jsf-impl increasing steadily the longer the app server is running.

> I can see the file count increase with every page load.
> What info is needed to dig into this deeper?
