Thank you for the reply ( marioroy? )! In the first example, it was necessary to move the SIG handlers below the `mce_loop` statement, else it gave error: `MCE::exit: method is not allowed by the manager process at mce.pl line + 19.` [download] After moving the SIG handlers, it gives no error but does not appear to execute any of the code in END: `PID 18566 Forked child with 18568 Forked child with 18569 Forked child with 18571 Forked child with 18572 Forked child with 18570 Forked child with 18573 ^C ## mce.pl: caught signal (INT), exiting Killed` [download] The second example you provided gives the same result: `PID 18874 Forked child with 18877 Forked child with 18876 Forked child with 18879 Forked child with 18878 Forked child with 18880 Forked child with 18881 ^C ## mce3.pl: caught signal (INT), exiting Killed` [download] Note that the program runs successfully if left to complete: PID 19017 Forked child with 19019 Forked child with 19020 Forked child with 19023 Forked child with 19022 Forked child with 19024 Forked child with 19021 Forked child with 19019 Forked child with 19020 Forked child with 19022 Forked child with 19023 19020 1491572765.74874 (Child) in END 19019 1491572765.75111 (Child) in END 19024 1491572765.75325 (Child) in END 19022 1491572765.7533 (Child) in END 19021 1491572765.7552 (Child) in END 19023 1491572765.75711 (Child) in END 19017 1491572765.75939 (Parent) in END Parent is ready to dump Dumping: $VAR1 = { '00 19019' => '1491572745.74377', '01 19019' => '1491572746.74401', '02 19019' => '1491572747.74421', '03 19019' => '1491572748.74441', '04 19019' => '1491572749.74457', '05 19019' => '1491572750.74473', '06 19019' => '1491572751.74493', '07 19019' => '1491572752.7451', '08 19019' => '1491572753.74529', '09 19019' => '1491572754.7455', '10 19020' => '1491572745.7436', '11 19020' => '1491572746.74385', '12 19020' => '1491572747.74405', '13 19020' => '1491572748.74427', ... } [download] Thank you again for the help.

$SIG{INT} points to MCE::Signal::stop_and_exit by MCE::Signal. Ditto for $SIG{TERM}. Folks can override that if need be like you've done. In that case, the following is needed. `$SIG{'TERM'} = sub { if (MCE->wid > 0) { # worker MCE->exit(0); } else { # parent MCE::Signal::stop_and_exit('TERM'); } };` [download]	[reply] [d/l]

MCE->exit is important, before the worker exits. The manager process substracts the count by one and reaps the worker.	[reply]
