Which version of Net::Server ? Are you sure the process 2440
really did not exist (perhaps it existed as a result of starting
amavisd twice by mistake) ? Please see subroutine check_pid_file
in /usr/lib/perl5/vendor_perl/5.8.8/Net/Server/Daemonize.pm,
it does try to check if a process whose ID was found in a pid file
does exist, and it aborts only if finding a process is possible
and the process was found. But I see the procedure is Linux-specific
for no good reason - the kill 0 would do the same job more portably.
