Given that you only use the hardware to full capacity when you scan
larger files it might actually be a hardware problem.
It took me a week continues scanning to find faulty memory in a
Barracuda unit that would bail out with a dying clamd process multiple
times per day.
While most of the times you get some indication of hardware problems
there is the occasional situation where you seem to be chasing software
problems based on your findings only to find out it is actually a
hardware problem instead.
So my E 0.02 is on a hardware problem for now.
