How long have those machines been online? There is a discussion about the 2.4.21rc kernels on the SE Linux mailing list. Machines running 2.4.21rc kernels seem to have a kernel memory leak which makes them unusably slow. Opinion is divided on whether this is a kernel issue or a SE Linux issue. I don't believe that it is SE Linux at fault as the SE code we are using is a straight port from 2.4.20 (and should run equally well as on 2.4.20). However other people have seen some evidence to suggest that the problem may only occur on SE Linux machines (I don't run any non-SE machines at the moment for testing). I would like to see some more data-points about the reliability of 2.4.20-rc kernels. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
