Is there a document somewhere which not only lists the error code numbers and a brief explanation of the error, but also lists a possible resolution to the specific error. Most documentation that I'm able to find only seems to repeat the error code and error description - that doesn't really help much.
kb.mcafee.com is the place to look for resolutions. Most of the error codes will never be seen, they are internal checks, to be honest, I've never been able to reproduce 90% of them.
They are there so we have an idea what went wrong, if strange things should go wrong.
