In an application I am working on, I am trying to temporarily disallow SIGHUPs from interupting my program (normally they will signal for it to reload configuration information). In these particular circumstances, the program is sent a SIGHUP quite frequently.

I am accomplishing this by setting: 

$SIG{HUP}  = 'IGNORE';

[download]
... as per the Perl documentation:

"You may also choose to assign the strings 'IGNORE' or 'DEFAULT' as the handler, in which case Perl will try to discard the signal or do the default thing."

The problem is that once in a while, I get the following message. The number of times that I get this message is not consistent with the number of times it is being sent a SIGHUP to be ignored; far more often than not, it 'does the right thing' and ignores the signal.

SIGHUP handler "IGNORE" not defined.

Why am I getting this message?

Thanks,
Scott
