Hello all,

I am trying to get syslogd to drop duplicate messages (-D option) but
it does not seem to work. Simple test:

$ syslogd -K -D
$ echo test | logger
$ echo test | logger
$ echo test | logger
$ dmesg | tail
[...]
syslogd started: BusyBox v1.22.0
root: test
root: test
root: test
$

However it seems to be doing "something" since it manages to drop
duplicates in this case:

$ killall syslogd; syslogd -K -D
$ echo test | logger ; echo test | logger ; echo test | logger

$ dmesg | tail
[...]
syslogd exiting
syslogd started: BusyBox v1.22.0
root: test
$

I am probably missing something obvious, but what is it ?

Thank you,
