Probably not. kswapd, if it is doing low-priority swapping, activates 4 times a second, not once every few seconds. However, swapping in general could be the cause, if there are background daemons waking up for a quick look at the world every so often. Also bear in mind that even reading a file will cause a write in a few seconds time, as the last-access timestamp gets updated on disk.
Cheers, Stephen. --- Stephen Tweedie <sct@dcs.ed.ac.uk> Department of Computer Science, Edinburgh University, Scotland.
