Unless you're using ECC RAM, bad RAM should still be #1 on your watchlist, closely followed by bad PSU. Even RAM that worked fine in the past can start exhibiting bit errors a few years later (maybe due to mechanical stress, i.e. vibrations or frequent temperature differences?) and esp. el cheapo PSUs have the tendency to degrade over time. Of course, a software bug may always be possible. Have you tried to get a core dump? If so, does the error always happen at the same place (backtrace / bt is your friend)? If the error keeps occurring at different locations, it's almost always dodgy hardware. > Regards, > Chris Maness -cpghost. -- Cordula's Web. http://www.cordula.ws/
