[jboss-jira] [JBoss JIRA] Updated: (JGRP-590) FC: messages > max_credits will block forever

FC: messages > max_credits will block forever --------------------------------------------- Key: JGRP-590 URL: http://jira.jboss.com/jira/browse/JGRP-590 Project: JGroups Issue Type: Task Reporter: Bela Ban Assigned To: Bela Ban Priority: Minor Fix For: 2.6, 2.5.1, 2.4.1 SP5 FC.down checks for the message size. If that size is greater than the credits left, we block until we get more credits from the receiver(s). However, if the message size is greater than *max_credits*, we will *never* have more than max_credits available to send the message, so we'd block forever ! To prevent running into this, we need to check (at startup time) in FC that - a fragmentation protocol is available (somewhere above the FC protocol) - that the max fragmentation size of the fragmentation protocol is smaller than max_credits We should also log a (fatal) error message if we receive a message whose size is greater than max_credits (this should *not* happen anymore though after the proposed change above)
