We have a large number of Sun workstations configured into a network of 7 file servers and approximately 50 diskless client workstations. Since installing the machines we have experienced a collection of what appears to be ethernet related problems or at least that is what the error messages on the Suns lead you to believe it is. The original batch of machines were 2/170s with 2/50 clients running UNIX 2.0. We have now added a 3/160 with some 3/75s running UNIX 3.0. We have noted that the error messages are much more common on the 3s than they are on the 2s. The messages that we are receiving on the Suns (in no particular order) are these: (Not all Suns produce all messages.) ie0: Ethernet jammed ie0: no carrier ie0: iebark reset ie: cmd not accepted panic: iechkcca We have VAXes, a DG, and Masscomps sharing this same ethernet and none are complaining of any problem, only the Suns. Further, in general, there is no apparent negative result to all of these messages. They just show up for awhile then go away, although crashes have been associated with some on occassion. Sun has been unable to provide any information or analysis of what might be causing these messages. Has anyone else experienced them? Has anyone figured out what causes them?
