There have been other IO problems, some of them truely bizarre. Things like certain SCSI busses getting a lowered priority based on what was installed on different HP-PA bus. ( I don't know the details of that one, it was given as the reason a machine had a goofy device layout) Something like that would only show up if the PA bus were close to being saturated, which would be a weird problem when you had lots of IO. Of course, this being HPUX, they might have had the same bug more than once. (It's a one time thing, it just happens a lot..., indeed) -- dscheidt@tumbolia.com Bipedalism is only a fad.
