Good point Rohit, I hadn't even thought of resource leaks. That might explain a lot.
Trouble is, the OS is so locked down that Task manager is not available. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rohit Gupta Sent: Monday, 14 May 2007 9:53 a.m. To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] Long running apps & weirdness Trevor, Two things. 1. We have something similar right now to do with Crystal Reports. I fairly sure that I have found the two problems in it. One is that callback from a dll is into a nested procedure with local variables and could be called after the object has been destroyed. The other is to do with strings. The more strings we pass to the dll the faster the crash. Basically memory/stack/registers are getting trashed leading to nonsense errors and even the app just disappearing. 2. Running out of resources. Open the task manager and keep an eye on GDI objects (the worst), User Obects, Handles etc GDI is the worst. Windows goes crazy, you cant even shut down. Old version of Nero used to do this. And ODBC driver for MSSQL did/does it too.
