Symptoms

After db consolidation with version 4.6.9 I upgraded towards 4.6.11, within the view flow there is no tracking of the data fields and activities. In the database, no records were created in the server log tables after the consolidation took place.
In the host server log and event viewer there is the following:

Application event log:
0 K2LogServer::ServerThread: 24129 A database error occurred : Could not find stored procedure 'Server.kLogServerUpdate'.

Diagnoses

The 'K2LogServer.dll' was registered in the GAC and it is not supposed to be.
Default location = "C:Program Files (x86)K2 blackpearlHost ServerBinHostedServers"
 

Resolution

The 'K2LogServer.dll' file was removed from the GAC which solved the issue. The assembly was also checked by labs and it seems okay.
