CFSCHEDULE gives "Connection Failure: Status code unavailable"

G'day

I've got a template being called as a scheduled task (via <cfschedule>).  On my local dev environment, it runs fine.  On the production server it errors with:

Connection Failure: Status code unavailable

Stack trace:

Other tasks on the production server run fine, as did this one up until this week (no changes to the code in that time, and no environmental changes that I'm aware of).

It's not the code in the template being called, because I factored that right down to a single <cfset>:

<cfset foo="bar">

And there's no Application.cfm consideration as I've put a "blocking" one in the same dir.

There's a bit of stuff on Google about this sort of thing, but none - that I've found - relate to my issue here.  I continue to google...

I'm not sure how to troubleshoot this, really... scheduled tasks have always just worked for me in the past, so haven't had any practise fixing problems.

Any thoughts?

Cheers.
