Additionally, if you *must* use these put them into a separate DRb server and make it the single control point for the resources.
I use Ruby's built-in IO functions to fetch some external RSS and do
some file caching. Would you consider this a hazard? I had a Rails site
that had gone 500 when it couldn't connect to the external feed. This
was due to a lack of error checking on my behalf. The weird thing was
that other Rails sites on the same box also stopped responding. I know
this is a vague problem description, I'll try and get to the logs and
see if I can spot anything.
