OMERROR_MSG notifications

Hi,

Recently we installeda a system, from scratch R12.2.9. DB 19c on AIX.

There is no user (just DBA , me who installed it). No functional.

But when WorkFlow mailer is running we receive automatically, without no action from us , about 300 or more notifications per day.

The message name are:

Select distinct MESSAGE_NAME from WF_NOTIFICATIONS where BEGIN_DATE > sysdate -4

MESSAGE_NAME

------------------------------

OMERROR_MSG

How can we stop creating notifications and sending emails?

Thanks.
