"Connection Reset by Peer"

    Hi All,
     
    I would like to know in which case the "Connection reset by peer" exception will occur? What is the influence of "Connection reset by peer" and how to solve it?
     
    Thanks!

    Hello!

    Usually it means that your TCP stack has decided to close connection which was not explicitly closed by application code.

    WRT solving it, you need to understand where it happens first. Can you show a stack trace?

    Hello, thanks for your reply！
     
    The scene we use is to gradually increase the number of Ignite client nodes, establish a socket connection with the Ignite server cluster, and then read and write data. The upper limit of the number of client nodes and connections we set is 4000. Is this number of connections too high?
     
    The error message of the call stack is as follows:
     
    java.io.IOException: Connection reset by peer

    Hello!

    It is possible that your TCP stack has decided you are having too many connections and started shutting down some of those. However, "connection reset by peer" is outside of control by GridGain, we can only react to this event. You probably need to tune your network.
