| Re: Map point crashes on heavy traffic
The application crashes randomly but when I increased the number of requests, it started to crash more often like as I have about 2 request per second, map point crashes every 3-4 hours. I see that error message in event viewer in Windows. |

| Re: Map point crashes on heavy traffic
I'm not sure the error code off hand (did you try looking it up?) But I've seen something with Excel. The problem was that my code was feeding data to Excel quicker than it could handle it (eg. because the user is using scroll bar, or my code was particularly quick). This produced an error code that meant "busy" or something like that. Later versions of Excel are more susceptible. The solution is like Mike says: use an ON ERROR block. I trapped all errors, checked the error code for the "busy" code. If it was something else, then throw an exception ("Excel died" or something similar). If it is the busy code then sleep for 100ms or so and try again. If you're seeing your error twice a second, then I'd wait for 0.6 seconds. Richard
