[jboss-jira] [JBoss JIRA] (JGRP-1940) RPC responses should have the INTERNAL flag cleared

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13089575#comment-13089575 ] 

Bela Ban commented on JGRP-1940:
--------------------------------

If needed, the *Asynchronous Invocation API* can be used to create a {{Message}} and set flags as desired (e.g. {{INTERNAL}}), although that flag should never be used by application code.

> When an RPC request is retransmitted, it will be sent by {{NAKACK2}} or {{UNICAST3}} as {{INTERNAL}} message. If the RPC call returns a response, that response will also be {{INTERNAL}}, using up the internal thread pool.
> SOLUTION: clear the {{INTERNAL}} flag on an RPC response. JGroups uses the {{INTERNAL}} flag only with *messages*, never with *RPCs*.
