webMethods 10.3 Integration Server server.log contents

Can anybody tell me what does it mean when I find the following lines inside the IS server.log? Can anybody tell me what does /wm-message mean? And where does the 403 Service Error como from?

Thank you in advance.

Hi @sarquis ,
Please check for any errors in the error log under <install_dir>/instances//logs/WMERROR*.log at the same timestamp. There should be more information.

Regards,
Nagendra

Addendum:

when using IS Core Audit Database this is usually redirected to the database table WMERROR in the IS Core Audit Schema.
This can be viewed in the IS Admin UI in the Logs section.

Holger
