Problem Description:
We are seeing an issue where a CFHTTP calls seems to hang.  We then see that subsequent calls to that same CFHTTP end up in a hung state.
I’m attaching a stack trace for one instance of this.  We are seeing this multiple times a day but it is not reliably reproducible.
Here’s a description of the process.
We have a CFM page that does quite a bit of processing.  It will at one point make a CFHTTP request over to an authorization service.  When we see this issue it is always stuck on this call.  Subsequent requests to the original CFM page will then also get stuck on the same CFHTTP request.
We have verified that when this occurs we can call over to the page that the CFHTTP is requesting successfully.  We have tested that a different CFM page trying to use CFHTTP to the same resource also just hangs.
This is a production affecting issue for us.

Steps to Reproduce:
Repeatedly make a call using CFHTTP

Actual Result:
Calls to CFHTTP hang.

Expected Result:
Calls with CFHTTP return

Any Workarounds:
Had to back down to CF2016

We have been running this hotfix in Production the last 4 days. We have not seen a recurrence of the issue. It appears to have resolved the issue. Has this been incorporated into other patches? We're about to install the latest version of CF patches to our servers and I wonder if I need to keep this hotfix jar file in place. Thanks,

Thanks for your confirmation Michael. The fix is merged now into CF2018 branch and you can expect the fix to be present in next bug-fix hotfix (update) of ColdFusion2018.  You should keep the ColdFusion patched with this jar file till the next bug-fix HF is released.
