Re^2: hash elements are lost during reaping

[umitd]

Thanks for the reply. My fork routine saves pids of children in another hash to be compared in the processing routine:

sub StartJob {

    my $pid;
    my $sid = shift;

FORK: {
    if ($pid = fork) {
        #
        # This is the dispatcher!
        #
        $JobPIDs{$pid} = $sid;               # add pid, sid pair to th
+e hash
    }
    elsif ($pid == 0) {
....

The processing routine goes like this:

foreach $pid ( keys(%TrappedPIDs) ) {
        $rc = $TrappedPIDs{$pid};

        print " CHECKING: trapped pid: $pid    RC: $rc \n";
        
        if ( exists($JobPIDs{$pid}) and $rc == 0 ) {
           # do the processing ..
        }

%TrappedPIDs is a global hash. How come it can be different?

With you showing only small code fragments, it's rather hard to say. It's kind of like the old joke:

Goofus is searching for his diamond ring under a streetlamp.

Gallant comes to help, and after about 15 minutes, he says "Hey--about where were you standing when you lost the ring?".

Goofus: "Over there in the parking lot."

Gallant (surprised): "Well, then why are you looking over here?"

Goofus: "The light is better."
