OOBTest method testNonBlockingUnicastOOBMessage fails to correctly receive all OOB mssages ------------------------------------------------------------------------------------------- Key: JGRP-1794 URL: https://issues.jboss.org/browse/JGRP-1794 Project: JGroups Issue Type: Bug Affects Versions: 3.2.13 Environment: Solaris, RHEL, Windows, HPUX tcp stack only Reporter: Richard Achmatowicz Assignee: Bela Ban Fix For: 3.2.13 This test fails regularly on multiple platforms. It doesn't fail all the time, but perhaps on 5/10 platform executions. The test consists of a sender and a receiver. The receiver B will receive OOB messages but blocks on a latch for 25 seconds when it receives a non-OOB message. After 25 seconds, it unblocks and continues receiving The test does this: - send 1 regular message from A -> B - send 9 OOB meesages from A -> B - wait 20 seconds for messages to arrive - check that all 9 OOB messages have arrived - unblock the latch - check that all 10 message have arrived The test failures all involve the first 9 OOB messages not arriving completely. For example, sample lists of received messages before the first 20 second interval are: [3,2,6,8,9,10,4] [2,3,4,8,9,5] [2,3,4,8,7,9] [2,3,5,4,6] So, it appears that either the messages are slow to arrive or not arriving at all. A correct result looks like this: {noformat} list = [2, 4, 3, 7, 8, 9, 10, 5, 6] [main]: releasing latch list = [2, 4, 3, 7, 8, 9, 10, 5, 6, 1] {noformat}
