Reported from mailing list

I am running httpd-2.4.12 and mod_nss-1.0.11 built from source and am running into an issue where I occasionally get an error where mod_nss throws the following exception

SSL Proxy: I don't have the name of the host we're supposed to connect to so I can't verify that we are connecting to who we think we should be. Giving up.

What is strange is that the issue does not happen consistently, sometimes the error will occur after the first request, other times after the 5000th.

Any thoughts about what could be causing this?

The following is what I'm seeing in the log
