I am running Windows NT SP5 on a Pentium II 350 with 64 MB of RAM. Sometimes I get the following error message:

This instruction ar 0x3071EA91 referenced memory at 0x00000014. The memory could not be read.

Does that meand bad memory?

What are you doing when this error occurs?  You may want to upgrade to SP6 although that may cause headaches also.  I doubt it's an issue of bad memory though anything is possible.

It simply means you're running a buggy application that tries to read from a protected memory area. Each process running on NT has a 'virtual' 4GB address space, which does not correspond to physical memory addresses in RAM. Accessing meory at a NULL address is one of the most common programming errors, and to catch these faults, NT protects the lowest memory address range (1 page == 4096 bytes on intel machines). Now, if an application tries to access this memory area, the NT kernel is notified and terminates the bogus app with an error message like the one you have seen. Your 'physical' memory in your RAM is not affected by this and seems to be OK - if not, you'd have seen a 'Blue Screen of Death' ;-)

Thank you both.  I do get a lot of blue screens as well. Usually I will get a warning that I am running low on virtual memory.

I think the error message described in the question happens mostly in an application I wrote so maybe there is something wrong with it.
