Unexpected Condition during run time in DOS 4.0

[PhilUK]

My users are experiencing "Unexepected condition: GP nnnn" problems, "randomly" during run time. The majority of these start with 17, last 2 digits vary.

These occur in serveral processes within the application, not just one process. The same process will be successful for a number of times, then fail, then success, etc!!

Does anyone else have any similar experiences or ideas as the best things to look at?

System: Paradox DOS4.0, Win98, Novell network. Started Jan92, evolved ever since, with a number of different programmers. The app is basically menu with a number of processes which run to conclusion, then return to menu.

Thanks

PhilUK,

Are you using any commend line switches? If so, which ones?

At the very least, you should be using -extk 16000

Hope this helps...

Footpad - thanks for your swift reply.
The command line switches we have used since 5/5/94 are

Paradox -space -norealheap -codepool 1200 "start script"

Of course!!, our PCs have moved on a bit since then! Even though I knew of the 16Mb limit, I needed you to tell me to get me thinking on it.

The Windows Shortcut is used to limit memory, but this may not be reliable (or set on all PC).

I will add the -extk 16000 for one of our PC, run the main problem process and let you know how we fair. A few years ago, this fixed a similar problem for me at a client, where the Novell VLM were loaded into Extended Memory, which Paradox would use after some time, thus taking out netware drives where the data was held!

Happy New Year!
"-extk 16000" has helped. Big improvement, too early to say whether it has solved all problems, but thanks again.
