[jboss-jira] [JBoss JIRA] Created: (JGRP-374) Flow control should send new credits only *after* processing a message

Flow control should send new credits only *after* processing a message ---------------------------------------------------------------------- Key: JGRP-374 URL: http://jira.jboss.com/jira/browse/JGRP-374 Project: JGroups Issue Type: Feature Request Affects Versions: 2.4 Reporter: Bela Ban Assigned To: Bela Ban Fix For: 2.5 Currently, FC sends new credits (when the sender's credits drop below a threshold) *before* passing the message up. However, if the receiver takes a long time to process the message, we might queue up messages, possibly leading to OOMs. SOLUTION: in FC.up(), decrement the sender's credits by number of bytes received, but only send replenishment (if needed) *after* the message was passed up. This requires that passUp() includes delivery of the message to the receiver and we can be sure that, once passUp() returns, the message has been delivered. If we use a queue in Channel (e.g. using the pull model, Channel.receive()), this won't work. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
