Rohit Singh created ISPN-8821: --------------------------------- Summary: Infinispan 6.0.2 - Upgrading JGROUPS from ver 3.4.1 to ver 3.6.7 or later version Key: ISPN-8821 URL: https://issues.jboss.org/browse/ISPN-8821 Project: Infinispan Issue Type: Component Upgrade Environment: Oracle Linux - Exalogic/Exadata stack AS: Weblogic 12.1.3 DB: Oracle 12.1.0.2 JDK: 1.8 Reporter: Rohit Singh Priority: Critical Ours is a J2EE application (clustered across 4 nodes) internally using Infinispan Cache (Ver 6.0.2) with JGroups (Ver 3.4.1) as transport layer of our cache. Application had been running perfectly fine, but suddenly on one node, one cache-put got stuck with below stack trace. (Cause being blocked on org.jgroups.protocols.FlowControl$Credit.decrementIfEnoughCredits(FlowControl.java:567)). Now all further puts are getting stuck - blocked - on the same line on the same node. Other nodes are working fine in this respect. After discussing with [~belaban], he has suggested to upgrade to a later version of JGROUPS. *{color:red}Refer: https://issues.jboss.org/browse/JGRP-2250{color}* h2. *Now, we intend to use JGROUPS 3.6.7 or later version with INFINISPAN 6.0.2.* *Please suggest on the feasibility of the upgrading JGROUPS.* -- This message was sent by Atlassian JIRA (v7.5.0#75005)
