Map crashing after zooming in

[stevemclaughlin]

My flex app often crashes after zooming in, and i get the grey exclamation point in a circle!@?
What can I do to debug this?
I'm using flex 4.6, flex api 3.1, windows 7 professional 64 bit, 12g ram

thanks,

Debugging tips from adobe site with sample code:
Debugging basics
Breakpoints
Variables view, watchpoints, and Run to Line

Debugging tips from ArcGIS team:
ArcGIS API for Flex Debugging tips

You also need to install debug version of flash player

Good luck

Thanks, but that's not what I need,
I know how to debug my own actionscript code in flex, but it's not my code that is crashing,
I don't have anything running, I just scroll (zoom in )  on my mouse and sometimes I get the grey exclamation point of death.
and in the console I get:
[Unload SWF] C:\Users\user\Adobe\myproj\bin-debug\myapp.swf
Is there a maximum number of graphics that I can put on a map?
thanks,

Steve,

   There is a known API Bug that causes the GCOD (Gray Circle of Death) when a Polyline is highlighted (Selected) on a featurelayer and you zoom in where the extent of the selected polyline is beyond the maps view extent. Is this possibly the issue you are encountering? There is no resolution to this bug currently, but the workaround is to set the FeatureLayers selectionColor to NaN.

Thanks for the answer.I got same issue with 2.5.

is this issue got fixed in new versions(ArcGIS API 3.0 or 3.2 for Flex)?

Thanks.

I am having this same issue.  The GCOD has been my constant companion below 18K scale.
I am highlighting graphic polygons, not polylines, so possibly the error is related to both.  And yes, the polygons are extending beyond the current map extent at that scale.  But it also extends beyond the map extent at or above 18K scale and I never get the error.

I am not using a featureLayer, I am adding a graphic and a glow filter on hover over items in a list.  The error seems to be random, sometimes it crashes sometimes it does not.  Also some features crash while others do not.  The workaround seems to be not to add the glow filter. 

Using ArcGIS API for Flex 3.0.

Thanks,
Dan

The newest 3.5 release fixes a lot of these crashes, but I still get a crash once in a while while I zoom.
