SAP B1 HANA - Catalina.out full of WARN/ERROR msgs

[Private_Member_715690]

Hello all, we just discovered that the "catalina.out" log file handled by tomcat on the SAP HANA Server for SAP Business One have been growing slowly over a few months. Last week we discovered the log file was about 900GB. 

After cleaning this file and waiting for it to fill again with some data, we discovered that almost every second these errors are written in the file:

2024-12-02 07:47:47 ERROR [https-jsse-nio-40000-exec-52] com.sap.b1.sdk.oidc.core.handler.OAuth2Handler - not a valid token

I was not able to find any documentation or SAP note about this subject. Given the fact that it is writting these ERROR/WARN every seconds, I would like to know if this is normal or not and if it's not normal, how to correct this issue? 

File location is here: /hana/usr/sap/SAPBusinessOne/Common/tomcat/logs

Since we discovered this, at the moment we "clean" this file using the following cmd every day with cron: 

cat /dev/null > /hana/usr/sap/SAPBusinessOne/Common/tomcat/logs/catalina.out

Thank you.

Best regards
