14.1 Signal the Daemon | 511
The first two sections are always output; the third is output only if rule set debug_dumpstate
(?§14.1.5.3 on page 511) exists.
14.1.5.1 --- open file descriptors: ---
Eachopen file descriptor is displayed along withits current properties. These lines of
output can be numerous. In general form, they look like this:
num: fl=flags mode=mode type stats
Here, the num is the number of the open file descriptor. The other information in this line is
described in detail in our discussion of the -d2.9 debugging switch (?§15.7.9 on page 546).
14.1.5.2 --- connection cache: ---
When sending mail, outgoing connections are maintained for efficiency, and information
about those connections is cached. Before connecting to a remote host, for example, sendmail
checks its cache to see whether that host is down. If it is, it skips connecting to that
host.
This output is highly detailed and very complicated. See the -d11.1 debugging switch
(?§15.7.18 on page 550) for a full description.
14.1.5.3 --- ruleset debug_dumpstate returns stat ..., pv: ---
If the debug_dumpstate rule set* is defined in your configuration file, it will be called here,
and the previous line of output will be printed. The stat is the numeric representation of
the code returned by sendmail??™s internal rewrite( ) routine. That code will be either EX_OK
(0) if there were no parsing errors, EX_CONFIG (78) if there were, or EX_DATAERR (65)
if there was a fatal error (such as too much recursion, or if a replacement was out of
bounds).
