    Hi Rajesh,

    Sorry, I did not understand your case.

    Hi Vinoth Kumar,

    But please let me stress out that this is not an issue, it is normal that your server has an established connection for each connected client.

    Hi Vinoth Kumar,

    As you can see from the process id column, which always contains the same value, the java.exe process is just only one.
