Just for your information about our problem with TCPIP traffic suddenly stopping, and working again after a reboot or network restart or failing over to the backup OSA ports.
We are pretty sure it's the use of Layer 3 that is causing the problem. After changing eth0 config and changing to a vswitch using layer 2, problem goes away. So we have added a new setup of vswitches using layer 2, and changes the servers when we need to or can now, one by one. ________________________________________________ Tore Agblad System programmer, Volvo IT certified IT Architect Volvo Information Technology IMO Mainframe Databases & zOpen Gothenburg Dept.

Unless you can ping your default gateway, in which case it's something else entirely.
