RE: crashed db3 file

["Howard Chu" <hyc@highlandsun.com>]

Then you might try truncating some of the data to make it fit the page size.
The simplest thing to do would be to use dd to copy the file in page-size
chunks. E.g., if the database page size is 4K.
	dd if=id2entry.dbb of=copy.dbb bs=4k count=<database size modulo page size>
