Open Radar

 
I have a script that builds my project for CI, by calling xcodebuild for a few Schemes.

It has worked great, until today.

Starting this morning, I have been getting frequent (but not 100%) failures, with error messages like:

    2015-08-24 16:02:38.679 ibtoold[38183:509542] CFNetwork SSLHandshake failed (-9806)
    2015-08-24 16:02:38.949 ibtoold[38183:509542] CFNetwork SSLHandshake failed (-9802)
    2015-08-24 16:02:39.276 ibtoold[38183:509542] CFNetwork SSLHandshake failed (-9824)
    2015-08-24 16:02:39.373 ibtoold[38183:509542] NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824)


This has happened both on my CI machine (running Jenkins), and on my local machine.

When it happened on my local machine, I saw this in Console.app:
