- I concur--run the UETP tests to verify that what you write to memory stays
- wrote. The code is well exercised (tested); your results indicate memory
- is changing out from under you.
-
- If bad memory does not turn out to be the problem (you can probably rule it
- out quickly if your machine has parity memory (the error would have been
- noticed and logged) then you apparently have privileged code with a bug,
- writing to a wrong location.
-
- I have recently encounted, on more than one occasion, instances where the
- command tables for a process have mysteriously changed, and commands are
- no longer recognized (symbol tables too). The necessary system commands
- to accomplish these feats were not performed--a bug in one of the programs
- wrote to protected memory (it is only protected in user mode). We haven't
- identified the culprit, but we were able to verify the extent.
-
- I cannot give you any indication whether the bug was in a program distributed
- with VMS or one of our own devising. We have good reason to suspect both.
-
- Our only workaround was to say "it happened again" and log out and back in
- again (depending on the extent--usually most commands stopped working).
