Are you using a 32-bit or 64-bit build?
I had a similar problem with the 64-bit build and when I switch to the 32-bit build, it worked fine.

Hello,

I'm using Apache as a proxy to AJP, HTTP and HTTPS services.  I have an issue with Apache 2.4.12+ on Windows Server 2008 R2 where it occasionally stops responding to requests (can't open socket) unless they originate from the loopback adapter, which is resolved by restarting the Apache service.  I can see it still listening on 0.0.0.0:443 and I've got the Windows firewall disabled.  I searched the bug tracker and mailing list, but didn't find anyone with a similar issue.  I've got a decent amount of experience with Apache 2.2 on Windows and never saw an issue like this.  I see nothing in the error log when this happens.  I cannot provide a core dump because it may contain sensitive data.  If I knew how I would provide a thread dump.

I've tried reproducing the issue with various load tests and cannot.

I'm using the Apache Lounge VC14 build.  Would I be better off reporting this to them?  I needed some 2.4 features, so I used 2.4.12, which was the latest at the time.  I tried upgrading to 2.4.20 and I'm seeing the same problem.  I also enabled HTTP/2 when I upgraded to 2.4.20 because I hoped it was an APR issue and because HTTP/2 is nice to have.

Thanks,
Arthur
