I am gathering quite a collection of error Messages

[Dracus]

I have seen errors like these before. A number of times (not all of the times) it was due to memory locations going bad and not responding to request by the system, Had to replace the memory cards. Other times it was due to bad sectors on the HD which in turn messed up the OS. Still there were times where we really could not solve the problem and put the system in the back room to collect dust.
