In my logs I get all the time like every 5-3 minutes this error (Login failed for user 'cdi_usergh'.) and non of the job scheduled by this user. How can I find why is this happening. Thank you
check the source IP in the log entry (should say CLIENT: 127.0.0.1) and see where connection is coming from. Then look there for the reason (schedule jobs, users, applications running, etc).
