Bug ID: 65987
Summary: Infinite Loading Issue
Product: Apache httpd-2
Version: 2.4.48
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: All
Assignee: bugs@httpd.apache.org
Reporter: dstewart@vai.net
Target Milestone: ---
I am hosting a third-party websocket application on an instance of Apache
Tomcat(9.0.52). HTTPD/Apache Web is used in order to load balance multiple
instances of it. It's been our process for a long time, and works fine under
Apache Web 2.4.46, but we have begun to experience problems upon upgrading to
2.4.48 and higher.
Upon successfully logging in, we are receiving reports that occasionally that
loading part hangs. The Application halts the user's ability to do anything,
and displays that it is loading, but never finishes, and never appears to time
out. This only happens occasionally. Downgrading back to 2.4.46 completely
resolves the issue---it never happens again.
The Application is running on 2.4.48 using a Websocket Fallback rule, and
experiences other problems without that (it disconnects after a minute of
idling). The specific rule we need in place is
ProxyWebsocketFallbackToProxyHttp Off.
We haven't been able to spot anything in the logs pertaining to the issue,
either. As far as Apache and the Application are concerned, it appears
everything is going swimmingly. This problem occurs on all web browsers, and
nothing of note appears to come up in the network tab.
My balancer and proxy configurations are pasted below:
