Fellow monks,

I have run into an annoyance with a script that I am working on that is bedeviling me. Just to give you an idea of what I am up to, at the very highest functional level what the script does is as follows:

SCP some flat text files (CSV format) from two different machines that contain useful information I am going to use later in the process of creating my report
SCP some log files from two different machines to be corrolated
Marry the results and create two different reports
Email the results to a distribution list

The report is being run out of cron.

Where I am running into trouble randomly is in the steps where Net::SCP::Expect is being used to gather the information from the various machines. With no rhyme or reason and for randdom hosts I get the following spew back and my script dies:

When I run the report manually from an interactive terminal session it never breaks.

Has anybody elee run into this? Like I said above it does not happen every time, just when I'm not near my computer so I can run the report manually. Very annoying.

The version of {cpan://Net::SCP::Expect] is whatever the latest version on CPAN is. I just ran an update to make damn sure.
