I am running a Sun 3/280 (4.0.3) with two ALM boards and one MCP board. About twice a day the system crashes with a BUS error. The crash seems to be caused by various programs (sendmail,csh,getty,...). Has anyone experienced these problems and know of a possible solution? Thanks, Tom Caldwell Computer Center University of California, Santa Barbara Bitnet: 9531cald@ucsbuxa.bitnet Internet: 9531cald@ucsbuxa.ucsb.edu Here are the messages...
