[ https://issues.jboss.org/browse/JGRP-2039?page=com.atlassian.jira.plugin.... ] Bela Ban edited comment on JGRP-2039 at 7/11/16 4:17 AM: --------------------------------------------------------- Works as designed: when 5 RPCs which return futures are invoked, sometimes it took more than 5s for all futures to complete. The reason was that messages in batches (even of OOB messages) were processed by a thread from the OOB thread pool one-by-one. There are 2 solutions to make this processing parallel: # Use the Asynchronous Invocation API [1] # Mark messages as {{OOB}} and {{DONT_BUNDLE}}. These messages are then extracted from the batch at the receiver and dispatched individually by separate OOB threads. Unit test is {{RpcDispatcherTest.testMultipleFutures()}} [1] http://www.jgroups.org/manual/index.html#AsyncInvocation was (Author: belaban): Works as designed: when 5 RPCs which return futures are invoked, sometimes it took more than 5s for all futures to complete.
