Russell,

I am (was) running a vanilla 2.4.20 kernel and experienced a slow-down 
each night during virus scan. System would not respond to http during 
undefined moments. But rather repeatable each night, though each time at 
a different moment during the night. I've just rebooted into 2.4.19 to 
check whether its 2.4.20 or the results of hardware modification I did 2 
weeks ago. System is lightly loaded. file systems in use mostly Reiserfs 
and a spattering of left-over ext2.

Cheers,

Rudy
