You shouldn't use blocking IO, if you really want so much concurrent connections. I've never ever seen a native threading JVM, which were able to manage thousands of threads (Due to limitations of linux kernels 2.4) So i advise you to use java.nio (non-blocking IO, with selectors) BR Zsombor ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
