Do you know what the problem is?

I know that the RPI has pretty cheap design (like most of these super-cheap
SoC boards) and does suffer from a few problems. The most common one
is under-designed power supply. Together with the ultra-cheap wall-wart
supplies mostly used results in a quite decreased MTBF due to spikes/drops
on the power rails (BTW: soekris suffers from that too, just that a better
wall-wart supply doesn't help). Depending on the environment, in which
those boards are run, overheating might also be a problem.

Other than that, i am not aware of any software or hardware issues that
would cause the RPI, or any other board, to run unreliably.
