I am in the middle of a little script I'm writing that apparently needs more storage space than a standard tie'd hash can give me. This: 
$myhashinfo=new DB_File::HASHINFO;
$myhashinfo->{bsize}=65535;
unlink "revmap_check";
tie(%diskrevmap, "DB_File", "revmap_check", O_CREAT|O_RDWR, 0666, $myh
+ashinfo) or die "Unable to build on-disk database tie. $!\n";

... doesn't give me enough storage space, despite the fact that the {bsize} is as big as it can possibly get. Any larger (even a single integer) and it refuses to tie for me. At the moment, though, my script generates the following errors: 
HASH: Out of overflow pages.  Increase page size
It takes hours to run this script, so I have two questions:

1. Is my data going missing when those errors are generated?
2. What can I use that will give me a tie'd hash, and be able to store many GB of data in it?
