What version are you using? I’m not 100% certain, but I’d expect Geffon’s additions
to not have dedicated SSL threads would avoid the need for that patch as well? Brian? If I
recall, with a recent version of ATS, you’d simply set proxy.config.ssl.number.threads to
-1.

In either case, why is that patch not committed? Is there a Jira for it?

 Do you have certs set up in ssl_multicert.config? Or are you doing a blind tunnel on the
SSL traffic?
