Below is the changed fragment (old code is commented), and the problem is that it seems it's not multithreaded! I watched `ps fauxw` and during heavy load, while old version was runnig there were from 3 to 8 processes in beautiful tree, now it seems it has 1 child only at a time... Related problem is that during heavy load like this i get "connetcion refused" on clients...

Is there something wrong in this code? Maybe i just misunderstood Your "patching instructions"

Please Help!

my $dbh = DBI->connect("DBI:mysql:database=qmail;host=localhost",
                        "qmail", $pass,
                        {'RaiseError' => 1});

logmsg "server started on port $port";

my $waitedpid = 0;
my $paddr;

sub REAPER {    #!!!!!!!!!!!!v
        $waitedpid = wait;
        $SIG{CHLD} = \&REAPER;  # loathe sysV
        #logmsg "reaped $waitedpid" . ($? ? " with exit $?" : '');
}

$SIG{CHLD} = \&REAPER;
#!!!!!!!!!!!!!!^

for ( $waitedpid = 0;
  ($paddr = accept(Client,Server)) || $waitedpid;
  $waitedpid = 0, close Client)
  {
        next if $waitedpid and not $paddr;
        my($port,$iaddr) = sockaddr_in($paddr);
        my $name = gethostbyaddr($iaddr,AF_INET);

        logmsg "connection from $name [",
                inet_ntoa($iaddr), "]
                at port $port";
#do {
#    $kid = waitpid(-1,&WNOHANG);
#  } until $kid == -1;

        spawn sub {
                my $line = <STDIN>;
                chomp $line;
                my @param = split (/ /,$line);

I can't understand what code is supposed to be in your program and what isn't. Please post the actual code that you are using that has a problem.

Sorry, i was in little hurry...

Here's this fragment clear.

my $dbh = DBI->connect("DBI:mysql:database=qmail;host=localhost",
                        "qmail", $pass,
                        {'RaiseError' => 1});

logmsg "server started on port $port";

my $waitedpid = 0;
my $paddr;

for ( $waitedpid = 0;
  ($paddr = accept(Client,Server)) || $waitedpid;
  $waitedpid = 0, close Client)
  {
        next if $waitedpid and not $paddr;
        my($port,$iaddr) = sockaddr_in($paddr);
        my $name = gethostbyaddr($iaddr,AF_INET);

        logmsg "connection from $name [",
                inet_ntoa($iaddr), "]
                at port $port";
do {
    $kid = waitpid(-1,&WNOHANG);
  } until $kid == -1;

        spawn sub {
                my $line = <STDIN>;
                chomp $line;
                my @param = split (/ /,$line);
