Hi,
we suffer an incredible big issue after installing the CU7 of SQL Server 2012.
We have SSIS packages to load data, and when 2 queries from 2 SSIS packages are executed at the same time SQL Server become unresponsive!!!
the queries never ends, I stop the process after 9hours while normally takes 3hours.
I saw huge amount of memory wait types. never saw these wait types before.
without the CU7 there is no problem at all. (and before / after the CU7 I process the exact same data)
any idea???
