This is a 386dx-33 with ~1.5gig of IDE space... Version 2.1.7 would expire everything in a matter of hours, version 2.2-970510 on the same hardware takes days... The uucp traffic hasn't increased (I run uutraf every day, the number of bytes transferred remains fixed...) In top - I see that expire seems to be spending the majority of its time in biowait. As a happen-stance though; this is the machine that suffers from the 'daily panics'. It hasn't demonstrated that condition since the expires began taking so long... could the two be related? - Opinions? - - Dave Rivers - p.s. I'm open to suggestions as to how to speed this up. I'm already using the async mount option... didn't seem to make much difference...
