Recycled the event management with the following commands
Stop event management:
unicntrl stop opr
Start event management:
unicntrl start opr
After restarting the service now when we run caugui conlog we get the following error.
%CAOP_F_414, Database OPEN CURSOR failure on DB_OPEN, 03 January, 2018 16:16:27
The MSSQL user was locked. After unlocking the user now the event management loaded fine and the caugui conlog showed the entries.
