Hi,
I'm getting the following error in my log file. Normally it's every 10 minutes, but occasionally the frequency changes to 5min, 3,1,30sec, 10sec, 5sec and then every second. Weeks ago it took the db down with a disk full situation, but usually it clears after a few minutes of continuous errors.
Can anybody offer any thoughts for how to identify what this is, and how to correct the issue.
Thanks
Doug

Do you actually have a database named "root" and a db user named "root"? If
not, I'd check your client connection details to ensure you pass in the
database name and user.
Also, if you have a support contract, you could contact Greenplum -- I've
generally found them to be pretty responsive. Barring that, you could also
try posting to http://community.greenplum.com

No dbuser named Root. Don’t know who is the client, so having trouble identifying it.
So it sounds like the log messages are standard for a login attempt with unknown user.
I have a case open with GP.
Thanks for the thoughts.

That's my point, you don't have a db user named root, but you do (maybe) have a process running as root trying to connect to the db.

No, they are standard for root trying to connect to the database when you do not have a db user named root.

As Scott says, check your root crontab for any scripts that might
connect to the db, and check the connection string. The "[local]" part
means that the call is being initiated locally to that box, else it
would should the IP.

Could it be an automatic process, kicked off by cron or some such, running as root, and not specifying the db or user, therefore defaulting to root & root?
