[jira] [Commented] (ARTEMIS-4148) Too many open files in JMS consumer

["Justin Bertram (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARTEMIS-4148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17682220#comment-17682220 ] 

Justin Bertram commented on ARTEMIS-4148:
-----------------------------------------

I plugged the code you pasted into a local test, and I didn't see any accumulation of connections or evidence of unclosed sockets. I would expect that if there was a problem with a use-case this basic we would have seen reports about it before now or seen problems in the test-suite.

Can you provide a way to reproduce what you're seeing? If not, this issue will be closed as "Cannot Reproduce."
