I have found a 2GB ceiling per DB on my N800...
That is, once 2GB is reached in my VE Hybrid DB, MM closes if I attempt to download another map. If I rename the DB and start a new one everything is fine again... until I reach 2GB.

Is this unique to me, VE hybrid, or the tablet/OS ?
Or; is it a limitation of the DB file?

Both GDBM and Linux support large files (in excess of 2 GB), but that support has to be compiled into the binary. Either GDBM or Linux has NOT been compiled for Maemo with large file support.

One alternative (which is obviously not ideal) is to split your database into two separate files, e.g. one for the United States, one for Europe, etc.

A programmatic solution would be for Maemo Mapper to start splitting database files itself based on heuristics, but that complicates the implementation (potentially requiring Maemo Mapper to search multiple databases per tile access). I will have to investigate further....
