[jboss-jira] [JBoss JIRA] Commented: (JGRP-1079) OOB messages are discarded when pool size is small and rejection_policy = " discard"

Bela Ban commented on JGRP-1079:
--------------------------------

We also need to check for this flag in the regular removal look (after removeMany()): if we have OOB messages in the xmit_table, but the next message is *not* OOB, then we would simply discard the OOB message !

> When we multicast OOB messages, and (1) the OOB pool has only 1 or 2 max threads, (2) no queue and (3) a rejection_policy of "discard", then we can lose messages. The messages are delivered (and retransmitted, if needed) correctly by NAKACK, but on the receiver side, the extraction policy is incorrect.
> The unit test is OOBTest.testOOBMessageLoss().
