It's not just the kernel that needs to be updated; pretty much everything gets updated over the course of a year or more. It seems mor= e likely to be the apps than the kernel; 2.4.18 is indeed the latest stable, but which Red Hat version do you have? 2.4.18-10 is, I think, the latest patch, but RH8.0 uses 2.4.18-14. Also check your VMWare version - 3.2 is the latest. =20 I remember having many problems with RH7.1's stability, but when I move= d to 7.2 it fixed many of them (although others were introduced.) Applyin= g all the updates to 7.2 made it very much better. 7.3 seems pretty good too. I'm currently trying out 8 on my workstation, but I had a number o= f little problems with it because a number of key things work differently in 8.=20 You could experiment with upgrading one of the machines that's showing problems to a later version of RedHat (I wouldn't go for 8 yet as it's very new and although it seems really good, there may still be hidden bugs). Upgrading to 7.2 or even 7.3 should have very little impact on every da= y usage because the changes are mostly bug-fixes etc, so even if you have one machine at 7.3 and the rest at 7.1, it shouldn't generate too many problems.
