problem with ethernet interface?

[mday at zeno.mmwb.ucsf.edu]

Our 3/280 file server is crashing with the following message:

ie0: panic: iexmitdone: tbds out of sync
syncing disks... 5 5 3 done

ie0 corresponds to the subnet of diskless workstations, while ie1 is the
interface to the campus wide network.  Our Sun service engineer has
replaced the ethernet controller, but that hasn't solved the problem.  Has
anybody else seen this behaviour, and can anyone point me to a possible
cause?

Thanks,
