It's hard to see how that could be anything except an operating-system
bug. If we've been successfully writing on a file for awhile, there's
no way that another write should trigger a permission error. Unless
maybe they chose to report some sort of disk-quota-exceeded situation
as EPERM, but even so that choice seems wrong to me.
I'd suggest asking Sun^H^H^HOracle about this.
