Fairly high, yes. It has now been down for almost 48hours, which is probably just about as far as I can let it go. We've already promised our customers it will be back up Friday morning. Tomorrow is a holiday here, very fortunate. >>> but someone will if it goes on for another 12-15 hours.

That's an interesting comment - I guess I _have_ been relying on 1) the system only rarely needing a reboot and 2) a fast fsck when it happens. Do you have any insights to share wrt availability, large filesystems (up to 1Tb in our case) and millions of files?

That has been my experience too - right up until 28 April at around 20:00. :-( /Per Jessen, Zürich ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
