We recently upgraded to MR-CU9.
After the Upgrade, the DDM SQL Server process is running at 100% CPU for days!
There are some extremely poor performing SQL statements and blockings.
eg. Insert into PeriodExchangeRate().., Insert into TranslatedPeriodBalance()...., Update translatedBalances....
These performance problems did not exist prior to Upgrade from CU5.
Logs also show errors that were not there earlier.
So, this is two part problem.
I have deployed this CU in multiple configuration and have the same result with performance.
