             Summary: FD Monitor get stuck on TrasferQueueBundler
                 Key: JGRP-2486
                 URL: https://issues.redhat.com/browse/JGRP-2486
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 4.0.22
            Reporter: lukas brandl
            Assignee: Bela Ban
         Attachments: Main.java, stack-trace.txt

Apparently there is an issue in the FD protocol. When a cluster nodes is disconnected and the disconnect isn't handled by FD_SOCK, FD stops sending heartbeats after a while. This only happens when the queue of the TrasferQueueBundler fills up before the node is suspected.
The stack trace shows that the FD$Monitor is blocked by the bundler. This is probably the reason why the heartbeat timeouts are not noticed.
