in reply to thread failed to start?

On Linux, at least, each thread takes a slot in your process table, so you may be running into table size limits, which'd prevent thread starting. I'm not sure if Windows has a similar limitation, since it handles threads a bit differently.

    I was wondering too if there was some sort of file handle limit I was running in to. I have not been able to find out what it might be using perl 5.8.0 from activestate under win2k. I see a lot of talk about 256 but can't verify it. :-(

      yeah, it seems ActiveState 5.8.0 under WinXP, only 256 threads can be created. If Try to start more than that the program exits, no error, no warning. . . .: 

      use strict;
use threads;

my $num_threads = 0;

for(1..257) {
    my $thr = threads->new(\&threader);
    $num_threads++;
    print "$num_threads started\r";
}

print "$num_threads running\n";
sleep();

sub threader {
    sleep();
}
