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

             Summary: TcpCommunicationSpi.createTcpClient can cause OOME.
                 Key: IGNITE-5225
                 URL: https://issues.apache.org/jira/browse/IGNITE-5225
             Project: Ignite
          Issue Type: Bug
          Components: general
    Affects Versions: 2.0
            Reporter: Andrew Mashenkov
             Fix For: 2.1


TcpCommunicationSpi.filterReachable method doesn't shutdown executor correctly that causes OOME.
Possible reason is that user uses host name that can't be resolved somewhere in configuration.
