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.

After moving the SIG handlers, it gives no error but does not appear to execute any of the code in END:

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

^C
## mce3.pl: caught signal (INT), exiting

Thank you again for the help.


The way forward always starts with a minimal test.
