We had a problem at work that when a windows box would connect to a samba 
share with a lot of files in it, the kswapd was going nuts, even though we 
weren't low on memory at all.  Updating to the 2.4.18 or so of the later 
redhats fixed that issue.  It might be related.  I think the kflush daemon 
can get fooled into thinking it needs to get hoppin right now in older 
2.4.x kernels.
