fork( ) in Perl Help!!

fork( ) in Perl Help!!

fork( ) in Perl Help!!

I am having this problem:
I have Perl script that uses a “for” to launch many processes children using  “fork”, the problem is that:  the children are left zombies, and therefore arrives at a point in which we cannot create more processes .
We thank for any aid that can give us. Our code is:

for ($count = 0; $count <= 100; $count++) {
        FORK: {
                if ($pid = fork){
                        # father code  ;
                } elsif (defined $pid) {
                            # children code
      exit ;
                } elsif ($! =~ /Resource temporarily unavailable/){
                        print "Couldn’t create process";
                        sleep 5;
                        redo FORK;
                } else{
                        # failure
                        die "can’t fork: $! \n";


RE: fork( ) in Perl Help!!


You just have to wait() for your child processes. The fork() function returns the process id of the child just started and you can use that to wait() for it.

RE: fork( ) in Perl Help!!

Hello Mike : I would like to avoid using wait, because i dont want that the father waits for every child to finish, because i am launching *many* children, and i want them to run *all* concurrently Thank you very much.

RE: fork( ) in Perl Help!!


In which case they will all leave zombie process table entries. But that's the only resource they take up so there really isn't a problem with just increasing the size of your process table to accomdate them. What O/S are you running on?
