ListGrid, limit on number of total records?

[Principal Skiner]

I'm using the GWT RPC data source as shown in http://forums.smartclient.com/showthread.php?t=10850.
In my DB there is around 8 milion records. When grid is supposed to browse through all of those 8 milion records it behaves as if there are 40 50 to be browsed through. Scroll bar is pretty big, leaving no option to scroll past those 40 50 records.
However, when the search criteria matches 3 instead of 8 milion records the Grid works as expected. Scroll bar is tiny and scrolling through 3 milion records is possible.
The underlying query and logic in both cases work well.
Did I run into ListGrid limitation or a bug?

I feel for your users. I can't imagine ever allowing my users to scroll through more than a few thousand at most and more commonly less than 500. Sounds like additional filtering is more appropriate.

The more I dig into this issue the weirder it becomes. I've beend fiddling around with total number of rows returned by the query and grid works fine with 6100000 records. The magic number seems to be between 6.1M and 6.25M.

Any thoughts on this?
