  [Thu Nov 09 14:07:20.475211 2017] [mpm_event:notice] [pid 18349:tid 1400794=88005952]

  [09/Nov/2017:14:07:20] [Info] [CA WebAgent LLAWP] [18620]
  [Shutdown message=sent to the LLAWP. It should stop within 5 seconds ...] 

Environment

 

Web Agent 12.52 Any on OHS 12c on RedHat 64bit;

 

Cause

 

Out of the box, the OHS Node Manager will try to access the /dms/ resource to monitor its availability. If this resource cannot be reached or have delays in the answer, it might request the OHS Server to shutdown. If you protect root / or this resource /dms/, then the monitor will cause the OHS to shutdown.

 

Resolution

There are two solutions:

1) Open the AdminUI, and edit the Domain protecting the Web Agent running on OHS. In the Policies configuration, unprotect the /dms/ resource on your Oracle HTTP Server to solve the issue.

2) Unprotect /dms by using the ACO IgnoreUrl
