Out of memory during ridiculously large request

[Roger Williams]

Since an upgrade to 6.0 (perl 5.8.8) I am getting the following error:

>>Out of memory during ridiculously large request at
/usr/local/pop-before-smtp-1.36/pop-before-smtp line 355

Below is the offending line:

>> foreach (keys %db)

While googling I see there are other programs having the same issue.  Any
ideas on how to get perl/freebsd to let the program work?

Thanks,
Roger
