The 20 minute timeout is likely because of your keepalive interval. Try changing it to SENDGARBAGE FALSE. Some IP implementations aren't happy with ill-formed TCP packets and z/OS or an intervening firewall may well believe it to be an attack of some sort and close the connection. Packet traces are, of course, de rigeur to solve such problems. Alan Altmark z/VM Development IBM Endicott
