Actually, the problem is probably *NOT* "open files" at all. It sounds like you're running out of TCP/IP "ephemeral ports". If so, then you need to configure your OS to increase its "Max ports" ("ephemeral ports") range: EXAMPLE: NT/Windows 2000/XP: --------------------------- MaxUserPort registry entry HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters <= CREATE THE REGISTRY KEY "MaxUserPort" AND SET IT TO 10000 (OR HIGHER) Instead of editing ... |

Saying "Urgent" will only irritate people who may want to help you rather than getting you a quick answer. About the exception , it's hard to speculate anything without having a look at the code which is causing the problem so go ahead and paste the piece of code which is causing this. |

"Network is unreachable" is usually different than a timeout error in that it cannot even find where you want it to go, for example this can be the difference between having no wifi and having your wifi card off. First do the usual fiddling with your firewall to make sure the desired port is open, and then look into any network ... |

isInputShutdown() will always return false until shutdownInput() has been called. This does not occur when the socket is closed, as far as I could see.

Once they have returned true they will never again return false. In that manner the names ... |

So you searched every page on the Internet, every FTP site, every server, every host? I doubt it. Impossible. Anyway, to answer your question, it appears that you are handling the socket object outside of the class code you posted. Likely, your multi-threaded application is re-using the same socket object for every thread using it. Doing so will generate different Session ... |

I did a quick Google on your title. There are several threads. Some of them suggest it may be a hardware problem. I can't see how Java could generate that message from the code you've provided, as it wouldn't perform the operation that causes it (Socket.bind()) with an invalid address at all in this case. |
