DNS lookup failures: (Bad hostname)

[Bill Moseley]

On our production machines running LWP 6.04 and LWP::Protocol::https 6.03 I see a few times a day messages like:

500 Can't connect to dl.dropboxusercontent.com:443 (Bad hostname)

Yet, when I try fetching using lwp-request on the same machine the lookup works fine and I can fetch the content.

I suspect an issue with our own DNS, but I'm only aware of these lookup failures reported by LWP (we have lots of other non-Perl code that is doing lookups all day long).

Anyway, I just wanted to check here to see if anyone else has also seen hostname lookup failures for valid hostnames that might indicate a problem in the Perl libraries.

I'll look at adding more debugging -- like running dig or hostname on LWP failures of this type and see if those also fail at the same time.    Any other ideas for debugging?

Thanks,
