I'm doing some work with database queries and markers.  I am querying a database and then throwing up markers onto the map based on my query results.

I'm in the process of integrating a new version of my databade interface library and suddenly I am having issues where the map turns completely white with a red cross over it.  I know I am doing something wrong but I don't know what. The issues occurs when I add markers to the map (quantities of 200 or less).

The issue is intermitant and I suspect a timing issue regarding threads in my interface library.  What does the red cross mean? What I mean by that is, under what conditions does the red cross appear?

I am hoping that if I know why the red cross is appearing, I can fix the issue.
