             Summary: [Thin clients] Slow thin clients connection can lead to 
node failure with OOM
                 Key: IGNITE-20424
                 URL: https://issues.apache.org/jira/browse/IGNITE-20424
             Project: Ignite
          Issue Type: Task
            Reporter: Mikhail Petrov


All messages designated for the thin client are accumulated in the selector 
queue GridSelectorNioSessionImpl#queue before they are sent. Note that  
GridSelectorNioSessionImpl#queue  is unbound. If the thin client connection is 
slow and a huge number of messages with a large weight will be sent to it, 
GridSelectorNioSessionImpl#queue growing size can lead to OOM.

See https://issues.apache.org/jira/browse/IGNITE-20327 For real scenario to 
reproduce it.
