As I said already swap is part of your virtual memory and if you can't keep it available you should not be using it. It is the same as saying that your machine will die if half its RAM suddenly ceased to exist while it was running. Your recommendations so far have been "don't run processes which might swap" and "don't let swap be used". If you yourself are able to keep to both of these 100% of the time may I ask why you yourself have any swap at all? ometimes) or those of us in the real world where swap is desirable and may (sometimes) be used, a swap device failure *will* *take* *the* *machine* *down*. --aWh+LmBTmEUMKd3g Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFB3BSJIJm2TL8VSQsRAnBLAJ4poYvjd015R/dgVmU53RMRsExoCgCg+cgD kIn6c47kaisFd8wf5idSQw8= =JkWA -----END PGP SIGNATURE----- --aWh+LmBTmEUMKd3g--
