[jboss-jira] [JBoss JIRA] (AS7-4841) Poor handling of network failures between master Host Controller and slaves

Brian Stansberry created AS7-4841: ------------------------------------- Summary: Poor handling of network failures between master Host Controller and slaves Key: AS7-4841 URL: https://issues.jboss.org/browse/AS7-4841 Project: Application Server 7 Issue Type: Bug Components: Domain Management Affects Versions: 7.1.2.Final (EAP), 7.1.1.Final Reporter: Brian Stansberry Assignee: Brian Stansberry Priority: Blocker Fix For: 7.1.3.Final (EAP), 7.2.0.Alpha1 The detection and handling of network disruptions between slave HCs and masters is not working properly. 1) Network disruptions are not being detected until an operation is invoked from the master to the slave, and the detection will not happen until the TCP layer give up trying to transmit the message, which could take up to 20 mins with default linux tcp settings. 2) If no operation is invoked, or the TCP level detection has not happened yet, the master still regards the slave as registered. So if the network heals and the slave tries to reregister, the re-registration attempt will be denied. To solve this I am going to re-implement a variant of the ping-pong stuff we had in 7.0. -- This message is automatically generated by JIRA.
