I have a variety of systems running kernels ranging from
2.4.18 through 2.4.20 and am seeing fairly frequent
kernel oopsen. After the oops, kswapd is defunct, however
the systems are still running (they are dual CPU systems).
Has anyone seen this before, and is there a patch to fix
it yet ? Thanks.
