Help with Can't ignore signal CHLD, forcing to default Problem Can't Post


Have a fairly basic Perl program which I'm using system to create a file I can later check using XML->XMLin

But it seems the system call is generating a system error - Can't ignore signal CHLD, forcing to default

Program does run ok - but while I've read up on the error (as per below) - could someone explain to me in simple terms how what actually needs to be set /unset to stop this error being reported ? (i.e to stop output)

Any feedback appreciated



(W signal) Perl has detected that it is being run with the SIGCHLD
signal (sometimes known as SIGCLD) disabled. Since disabling this
signal will interfere with proper determination of exit status of child
processes, Perl has reset the signal to its default value. This
situation typically indicates that the parent program under which Perl
may be running (e.g. cron) is being very careless.
