Hello, While investigating another problem, I did a netstat -I on our production SAP Linux App Servers. To my surprise, I am getting TX-ERRS on a hipersocket interface on two of our systems. The two systems have recently been converted to SLES11 SP2. The hipersocket device is connected t

Hi Ron, There is a bug in vmstat that results in zero IO. I have seen the same when investigating a CCL problem. So don't (for now) rely on the IO counter in VMSTAT. I did report it to IBM and I guess through that channel an update for vmstat will be created. Regards, Berry. -Original Me
