Bela Ban commented on JGRP-1794:
--------------------------------

OK, increasing the OOB pool size from min=1/max=2 to min=4/max=8 (like in master) seemed to fix this. Can't reproduce the error anymore with UDP. Now trying TCP...

> 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}
