Oracle HTTP Server Hangs when Accessing Application via Reverse Proxy Configuration (Doc ID 2413783.1)

Last updated on AUGUST 16, 2021

Applies to:

Oracle HTTP Server - Version 11.1.1.7.0 and later
Information in this document applies to any platform.

Symptoms

Using Oracle HTTP Server(OHS) as a reverse proxy to another OHS, the system hangs at indeterminate times.  Restarting OHS resolves the issue.  OHS Front-end is in an inconsistent state after the OHS Back-end temporarily stops responding.

The OHS log files have the following entries during the time of issue.

Front-end OHS log

 

Changes

Periodically an external application called from the OHS back-end was restarted.  After the restart, this application's requests were returned to the back-end and collapsed.

Restarted the OHS back-end and front-end although the problem was only in the back-end OHS.
