stack overflow

[BruceN]

We have a customer doing beta testing on a new version with some new features. One of those newbies is recurrent invoicing with credit card processing. In running the routine (for several hundred customers) they get this crash:

I'm at a loss as to how to effectively debug this.

I'm guessing that the 'stack' (whatever is 'stacked') is getting filled with something from each invoice that isn't getting destroyed/released or whatever gets done to remove something from the stack.

Is there a way to view the actual 'stack' during running to see what is getting thrown on (in?) it repetitively until it overflows. Is there a better way to find the problem?

As always, I humbly bow before the wizards

i would say it happend in GUI Thread (800). try to increase STACK in your *.XPJ

... btw. where are your MagicHelp come from ... DBF or Array ?

"Module EH" means the error is caused by the error handler. You may have an endless iteration/recursion there, maybe in your "errorsys.prg". The error causing this is something else.

Yes ... this is the Reason why he got a XppFatal.log but the Error itself happend in other Thread.

Error is in SYS Thread-ID: 800 so it is the GUI Thread ... most seen with MagicHelp / DBF and own Thread

@bruce : did you have some own Eventhandler or did you use 4th Parameter "Timeout" in AppEvent() ?
