I am using K2 BlackPearl 4.6.5, and I am getting the below errors on regular basis in the Windows Event Viewer:
24148
The User Manager 127.0.0.1 returned an empty queue. (hundreds of this error)
64007 Provider did not return a result for K2:DomainUserName on GetUser
64005 Failed to resolve '2966': K2:DomainUserName.
64005 Failed to resolve 'K2:DomainUserName': The specified account does not exist. Resolving User:DomainUserName.
64007 Violation of PRIMARY KEY constraint 'PK_Identity_IdentityUpdate'. Cannot insert duplicate key in object 'Identity.IdentityUpdate'. The duplicate key value is (-68820447, K2:DomainUserName , 1).
The statement has been terminated.
1 Invalid Serial Number:
64007 Transaction (Process ID 330) was deadlocked on lock resources with
another process and has been chosen as the deadlock victim. Rerun the
transaction. (this one does not appear so often but still it is regular)
The Problem is that I don't know how these errors happen, even if the server is idle (no user actions) the first 5 errors keep generating.
I am doubting that may be those errors arise when K2 synchronizes/updates Role members.
I have users from 4 domains.
K2 is using windows authentication, not Kerberos, and installed on two form ends.
