Finally, make sure you don't have anything funky going on with the hard drives... I recall a while ago (yes, ok, it was on windows) a HDD dropped into PIO mode and utterly crippled the entire machine...
That brings back bad memories. :-) Another issue we've had is a silently failing hard disk. It would just lock the firewall for seconds at a time with nothing out of the ordinary showing anywhere. Nothing in the logs, normal top, ps etc. It would just become unresponsive then come back. So a Neil's ghost to another box is a good idea, it'll rule out flacky hardware. -- ------------------------------------------------------------------------ Jean-Francois Pirus <jfp(a)clearfield.com> Senior Software Engineer Phone (+64-9) 358 2081 Clearfield Software Ltd Fax (+64-9) 358 2083 4th Floor 8-10 Whitaker Place Mob (+64-21) 640 779 P O Box 3901 Auckland, New Zealand ------------------------------------------------------------------------
