Issue/Introduction

In AdminUI, login and logout were successfully done as well as administrator operations such as creating new objects.

Still, the below error was found in server.log:

2020-03-16 11:09:10,303 ERROR [io.undertow.request] (default task-3) Undertow request failed HttpServerExchange{ GET /iam/siteminder/app/ui7/index.jsp}: java.nio.BufferOverflowException
    at java.nio.DirectByteBuffer.put(DirectByteBuffer.java:363) [rt.jar:1.8.0_212]

Questions:

1. Is this message ignorable? Otherwise, I need the cause and the resolution.
2. A KD mentions the same error, but the solution doesn't remove the error (1).

Resolution

1. The exception is due to WildFly as referenced in the same KD article (1).
   
   As far as administrative operations are concerned, the exception should have no impact and be ignored.
    
2. Follow the article to prevent any other potential problems (1).
   
   Note that the Wildfly third-party has been upgraded to version 24.0.1 in SiteMinder 12.8SP8CR01 (2).

Additional Information

1. Error: java.lang.OutOfMemoryError: Java heap space in AdminUI WAMUI
