This is an odd one. It's on an OfficePC currently running KSS 8.3.16 B112. I've got a math-heavy program that I'm torture-testing by running it for several thousand cycles, throwing random numbers at it each cycle.
Overnight, I got this message about 120 times. Each time the error is the same: the .DAT file of one of my math support modules "cannot be accessed". It's obviously not a regular occurrence, b/c that module would have been accessed several thousand times overnight, and the message only occurs a small % of those times.
It's a Notification message, and it doesn't stop the program execution. The message source module is shown as "CheckArguments," and the number is simply "21" -- no "KSS" prefix.
As far as I can tell, nothing is actually going wrong, but this puzzles me. Since I'm reading/writing some of the .DAT file static variables every cycle, I would expect that if the file really could not be accessed, the program would be halted.
At the moment, I'm guessing that this is just a bogus message being thrown by KSS. But I'm curious as to whether anyone else has ever stumbled over this one.
