Perhaps some ideas: - Windows talk "everywhere", understand : it send lot of packets for ARP, uPnp, Netbios, etc... More than Linux on this point. - If you use a hub, and not a switch, you can have "lot" of collisions on the network. What is the result on a switch? - Do you use ARP_QUEUEING? There was a problem with this option in previous releases. - Does your ethernet driver call directly etharp_ip_input on receive? This could cause problems inside ARP table (concurrent access not protected), and "load" your target if you receive lot of packets... ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr ==================================== P Avant d'imprimer, penser à l'environnement

Do you think pinging may cause the same effect because I'm pinging the devices while packets are flying. Some times pinging was ok, sometimes it crushed the boards.
