My boss sent me this email today, I was out of the office attending a NetScout presentation. Have anyone seen this kind of problem or know what is going on here.


The new mainframe has an error code your network group may want to investigate. These message come overwhelmingly from just Marlin and Hamilton. According to the message manual, the check sum of an incoming TCP packet is incorrect. The corrupted packet is discarded. If the message occurs frequently , check for faulty communications paths. This is just a sample from this afternoon. We get these all day long. I wonder if these folks are in the same switch.
