Sendmail, 3rd Edition

Name

-d38.9

Synopsis

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 16-11.
