TCP timeout with error message(java.net.SocketException: Software caused connection abort:recv fail)

[john price]

My TCP client times out after 9-10 minutes. I have tested this on multiple computers. The server remains up, fine, and running with no other errors. This is the error message displayed on the server cmd line:

java.net.SocketException: Software caused connection abort: recv failed

This is the error I receive on the client:

java.lang.StringIndexOutOfBoundsException: String index out of range: 0
        at java.lang.String.charAt(Unknown Source)
        at SimpleChatClient$IncomingReader.run(SimpleChatClient.java:667)
        at java.lang.Thread.run(Unknown Source)

What does this mean and how can I fix it?
Thanks,

In this case you are getting empty String thats why you are getting StringIndexOutOfBoundsException.

In first case just check whether your firewall is blocking the port you are using.

I am running the server and the client...Connected to my IP address and have port forwarding set up. Works until 9-10 minutes. Then, sets off error. Just put up a try and catch clause around that line. Get slightly different error:

java.lang.StringIndexOutOfBoundsException: String index out of range: -1
        at java.lang.String.substring(Unknown Source)
        at java.lang.String.substring(Unknown Source)

I had to go into Windows to fix this:
Control Panel > Installed Updated > Turn Windows Features on or Off > (CheckBox) Simple TCPIP services (i.e. echo, daytime etc)
Works like a charm now.
