[ome-devel] Failed root logins at midnight

[Aleksandra Tarkowska (Staff)]

Hi Rainer,

If you are running OMERO.web client, could you check if there are any request around the same time in nginx logs?

Kind regards

Dear OME-Team,

since a couple of days we get notifications about failed root logins on our OMERO server, predominantly happening exactly at midnight (00:00:nn):

The only exception observed so far is the event recorded at "2016-10-24 17:36:54" marked with a ">": it occured when we had to restart the OMERO services because some processes/functions were no longer responsive.

Any ideas what kind of internal OMERO process management could cause those notifications? And why always exactly at midnight?

Any feedback would be appreciated.

Thanks a lot for your support, best,
-Rainer
