[Laura Armstrong]

Hi.  Our system crashes fairly often with the following panic:

panic: mclput
syncing disks... 4 4 ENTER:
trap address 0x8, pid 25335, pc = f0162f0, sr = 2100, stkfmt b, context 2
Bus Error Reg 40<PROTERR>
data fault address 20f1a faultc 0 faultb 0 dfault 1 rw 0 size 2 fcode 5

A0-A7  f0d3f98 f08c24c f07ca84 cae0000 f07f6b0 20f06 f07ca1c f07ca08

We have a Sun 3/280 running SunOS 3.4.  Any help interpreting the
above panic is greatly appreciated.
