----------------------------------------

             Summary: GridDeferredAckMessageSender can cause starvation in stripe pool on
unstable topology.
                 Key: IGNITE-5527
                 URL: https://issues.apache.org/jira/browse/IGNITE-5527
             Project: Ignite
          Issue Type: Bug
          Components: clients, general
            Reporter: Andrew Mashenkov
             Fix For: 2.1


Slow or failed client can cause starvation in stripe-pool.

GridDeferredAckMessageSender.sendDeferredAckMessage() can stucks when add message to buffer
while other thread trying to send this buffer.

Seems, we shouldn't wait for readLock in DeferredAckMessageBuffer.add() method and return
false immediately.
