We've been getting numerous crashes on our Sun-4/280 and our Sun dealer
here hasn't been able to solve the problem. The console reports a "BAD
TRAP" followed by errors such as "data fault", "text fault", and "memory
alignment error". The system usually reboots itself but not always. So far
we replaced three boards, including the CPU, memory, and ethernet boards.
Has anyone out there ever seen this type of crash and knows what the root
of the problem is?

We had the same problem and it took Sun 8 months to figure out what it was. We replaced the CPU board many times. Disk controllers were swapped. We rearranged the boards on the bus. What the problem turned out to be was that the memory would sometimes not respond fast enough and you would get a `BAD TRAP' error. You do not mention what size memory board you have, but if it is the 32Mb one make sure it is part # 501-1254 04 Rev 50. Once we got one of these babys installed we run for weeks without a crash.
