This could be induced by a bad grounding of the main console. It happened to me
a few times when I've touched on of the panels. You get a slight jolt and then
a few error messages when the hard drive unit is activated. This is slightly
annoying but doesn't lead to a real security problem for the PDP-11.
In my case Apache crashes, but I didn't find any proofs of any files tempered
with.
