I believe the garbage packet would only be set if the actual socket is defined to use keepalive, hence why I suggested to code KEEPALIVE=YES on the RSCS link parm. It is possible the this is already happening, but why then is socket on the z/OS side being broken? Best Regards, Les Geer IBM z/VM and Linux Development
