Description Wolfram Schneider freebsd_committer freebsd_triage 2022-01-17 15:28:48 UTC 
While testing locate(1) with a very large database (>2GB apparent size) I noticed that it sometimes does not work with mmap (default).

Workaround: use the -s flag and run with stdio library (ca. 30% slower than mmap).

Note:  you should not be affected by this issue if you have less than 500 mio files (or < 30TB) on your partition.

    correct type of mmap len parameter

    Using locate -m on a database > 2GB should work now.
