hi smart guys, i've written a simple perl server running under sunos5.8 as part of a bigger project. this server is set up to fork a child for each request. the server has to interact with a mysql db, so i used the standard dbi module to query my data source. i've modified a bit the standard reaping code i found in the perlipc manpage to suit my needs but it seems that some SIGCHLDs are just ignored, letting orphans children wandering about... soon, i realized the process table fills up with defunct processes over a relatively short running time, causing hell of trouble! i'm almost sure the problem resides in the reaping code. the number of requests per sec is very high, so i suppose some SIGCHLD handlings overlap. any ideas? thanks in advance...
my $waitedpid = 0;
my %dbh_pool = ();
sub REAPER
{
$waitedpid = waitpid(-1,WNOHANG);
$SIG{CHLD} = \&REAPER;
if (defined $waitedpid && $dbh_pool{$waitedpid}{"Active"}) {
$dbh_pool{$waitedpid}->disconnect;
delete $dbh_pool{$waitedpid};
}
}
$SIG{CHLD} = \&REAPER;
