Based on the stack trace it looks like you have nuget.org package mirroring enabled. You can disable this feature (enabled by default) by editing Web.config and changing the app setting NuGet.Lucene.Web:packageMirrorTargetUrl to be blank.

http://www.nuget.org/ is experiencing degraded performance today and I suspect this is why you are experiencing the issue.

This error should be handled and logged without propagating out to clients, so it should be safe to ignore, although you may experience poor performance when the origin is slow to respond.

Thanks for the quick response, Chris! That seems to have gotten rid of the above and our server is able to create releases again!

I know you use Octopus (or used to) so I will include the following:

When testing the feed from the Octopus configuration screen it will throw an exception every time you search for a package. Perhaps it's the way Octopus is calling the Klondike API from this particular screen that causes the issue. I can post this on the Octopus support forum as well if needed.

[chriseldredge]

That looks suspiciously similar to OctopusDeploy/Issues#189 which was traced to a bug in Lucene.Net.Linq (https://github.com/themotleyfool/Lucene.Net.Linq/issues/48). What version of Klondike are you using?

Does /api/version on the Klondike server return some version data? It was added in more recent builds.

[JarrodJ83]

I'm not sure the version. The /api/version is not available in the version we run. Looks like I installed on 8/26/2013. It's been running like a champ so I never found a need to update it. Perhaps I will try updating to the latest release here soon.

Thanks again for all your help!

[chriseldredge]

Ah, that particular issue was fixed in v1.0.1 but there also have been plenty of other enhancements in later releases too.
