Invalid Cache Buffer Handle - Abend

We have a site that has abended with the above message, but with
2 different NLMS cited as the offending process.  One of these NLMs is written by us, but as far as I know, we do not use any cache buffer handles.  What does it all mean?

...could be bad RAM in the server. Is it starting to happen regularly? Does it only happen after the server's been up for a while? Any temperature discrepancies?

It's basically a statement letting you know that there's a problem with the memory addressing. Could be caused by hardware, could be a 3rd NLM using memory that it shouldn't be. Try loading the 2 offending NLMs in the protected ring, causing them to run in a different area of memory. Assuming there's no other NLMs involved, this should fix it. I'd be wary of doing this though. It may slow down the NLMs in the protected ring.

Not bad, but I'd like a little bit more detail.  Why does my NLM abend with this message if it doesnt use any file cache buffer handles?
