Sorry, I was throwing around numbers carelessly. I'll be more clear... http://rhn.redhat.com/errata/RHBA-2004-550.html talks about the kswapd issue and recommends upgrading to package kernel-2.4.21-27.EL. We actually didn't do this, because by the time we got around to it, the following had been released: http://rhn.redhat.com/errata/RHSA-2004-689.html doesn't talk about the kswapd issue, but recommends upgrading to kernel-2.4.21-27.0.1.EL for security reasons. Naturally, I assumed that this would include the "kswapd" fix in kernel-2.4.21-27.EL. In short we are presently running kernel-2.4.21-27.0.1.EL, and still have our problem. http://rhn.redhat.com/errata/RHSA-2005-043.html is what references the kernel-2.4.21-27.0.2.EL package. We had troubule with this upgrade and backed out. The point of my comments before was that I don't have any reason to think upgrading to this version will help with our problem, because the errata that announces it (2005-043) doesn't say anything about our problem. In short, I still have no confidence that anything we can do inside EL3 will solve our problem. This is why I'm tempted to try EL4... it seems possible that whatever is plaguing us with the 2.4 kernel won't do so under a 2.6 kernel. Thoughts?
