[infinispan-issues] [JBoss JIRA] Commented: (ISPN-937) FLUSH removal causing state transfer timeouts

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12586146#comment-12586146 ] 

Paul Ferraro commented on ISPN-937:
-----------------------------------

I spent a bit of time trying to manipulate the configuration to avoid the timeouts but without success.
For now, I've modified the problematic tests in the AS testsuite to add FLUSH to the stack - to circumvent the errors.  This is fine, since, by default, all the AS channels use FLUSH anyway.  The only reason these tests were using the default jgroups stack from infinispan was sheer laziness on my part.
