As of 2.2.20, all the issues I had with TCP lockups have gone away. Anyone know what the exact cause of this is? I'm afraid I don't understand the kernel's networking code enough to trace the changes that were made between 2.2.19 and 2.2.20. -Toth - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
