Hi Frank,
Is there a limit to the number of GDALDatasets that can be open at one time?
My program is set to automatically open raster images from a database.
There are over 2254 charts in the database. Each record has the path to
the actual file on disk.
In auto mode it gets to around 1004 or so files and then GDAL starts
returning "file not found" errors.
Patrick,
My first guess would be a file handle limit, as others have mentioned.

I'm afraid I don't understand this. The "says it can not be found"
and "opens them without issue" parts of this sentance seem to conflict.

disk. Also, if I change the sort on the database so it loads from the
bottom it has no problem opening the files in auto mode.
You are saying that you can open at 2254 charts fine if you open them in
a different order than the default? That is odd behavior!
At this point I'd normally try running in the debugger to track down
the failure, and/or running things under something like valgrind.
Best regards,
