[ome-devel] Failed root logins at midnight

[Rainer Poehlmann]

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):

   Blitz-0.log.4:2016-10-19 00:00:21,567 WARN  [  ome.security.auth.LoginAttemptListener] (Server-555) 2 failed logins

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
