-d38.9

Trace database map closings and appends Debug command-line switch

The -d38.9 debugging switch traces map closures for maps that can be closed:

ndbm_map_close(name, file, flags)
db_map_close(name, file, flags)
impl_map_close(name, file, flags)
ph_map_close(name): pmap-ph_fastclose=num
prog_map_lookup(name) failed (errno) -- closing
seq_map_close(name)

Here, the name is either the name you gave to the map with the K configuration command, or one assigned internally by sendmail (such as aliases.files). The file is the filename on disk that contains the database. The flags describe the specific features of a map. They are printed in hexadecimal, and the meanings of the values printed are listed in Table 15-10.
