Nearby won't do it for alpha particles - they have to come from inside. They can't travel far (a few centimeters in air, zero for anything with signifcant density), but the high mass of the particle does result in measurable damage if it hits something.
Back in the days when they were a problem, it was discovered that some chip carriers were slightly radioactive, creating some of the first true - albeit unintentional - hardware random number generators.

Do we know which file file.exists() is trying to check?
May be a good idea to run Tomcat with strace, to see exactly which file
is it trying to access.

Dark matter then. Like dark chocolate, as suggested by an earlier
poster. I keep being intrigued by the numerology here :
2 times 4 cores ..
4 Raid disks ..
8 reindeer ..
...
64 bit ..
it started a few days before Christmas (8 ?)..
That must be telling us something, we're just not smart enough yet to
figure it out.
