Bruce Schuchardt updated GEODE-7038: ------------------------------------ Issue Type: Bug (was: Improvement) > After auto-reconnect a server's multicat communications aren't working > correctly > -------------------------------------------------------------------------------- > > Key: GEODE-7038 > URL: https://issues.apache.org/jira/browse/GEODE-7038 > Project: Geode > Issue Type: Bug > Components: membership, messaging > Reporter: Bruce Schuchardt > Priority: Major > > This was observed in an server having multicast enabled on a Region. The > server went into a GC pause and was kicked out of the cluster. After > auto-reconnecting all of the servers were requested to shut down and they all > hung on destroy-region message responses. Statistics showed constant > multicast retransmission requests but no retransmissions being sent. > When a Region is configured to use multicast all of its cache operation > messages are multicast, including a destroy-region message. > Some time ago we decided to stop sending Join Request Responses during > discovery. These messages were responsible for carrying the JGroups > multicast message digest so that a joining member could install this digest > into its multicast protocol. Today these messages are only sent if a UDP > Diffie-Hellman algorithm has been specified. We need to also ensure that we > send these messages if multicast is enabled. > -- This message was sent by Atlassian JIRA (v7.6.14#76016)
