User Manager returned an empty queue

This means that you have defined groups in  [K2Server].[dbo].[_DestQueue]

It refreshes it every 10 minutes (I assume).

Either fix the data or you can delay it by updating Interval column abd NextUpdate.In following case it puts the interval to 24 hours and also will disappear till next year :-).

update [K2Server].[dbo].[_DestQueue]

set Interval=86400, NextUpdate='2013-05-14 15:04:11.673'

Hi Rajesh,

Dont modify the tables. Doing so will invalidate the support agreement with K2.

"User Manager 127.0.0.1 returned an empty queue" - This message is logged if your K2 roles does not have atleast one valid user. To stop the messages being logged, you must add atleast one user to all the roles, or delete the empty roles. Note: If the roles have AD groups, those groups must have atleast one user.

I am getting the same issue when trying to send an email back to the originator. This was working all fine in the past and the issue seems to match other issues related to the upgrade to 4.6.6.

The originator is defined and the calling "Get E-mail from User" method of the "Users and Groups" does return a valid value.

Any suggestion ? here is the log:
