[jboss-jira] [JBoss JIRA] (WFLY-5866) ClosedChannelException in SingleFileStore after server is shut down

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142773#comment-13142773 ] 

Paul Ferraro commented on WFLY-5866:
------------------------------------

Lowering the priority of this.  These exceptions do not indicate a bug - only that the cache store was stopped while other threads were loading entries from the store.  Per specification, FileChannel can be safely closed without corrupting writes.

> While the first two exceptions were logged only few times, the {{ClosedChannelException}} was logged tens of thousand times on perf19 and perf20.
> These exceptions don't seem to cause any sampling errors on the client side.
