If you don't need it, it opens a whole can of worms. I think 2.4.9-34 is the most recent errata non-enterprise kernel for 7.2 (and 7.1, which I'm running), and I haven't seen anything like this with that kernel. > I can't figure out what is causing kswapd and kreclaimd to go crazy when > the dump program runs, and it only happens on the dump-host.
