I have a problem in that the RDS service on the cell manager uses up all of the memory when an IDB backup is run and won't release it until the RDS service is restarted. This happens on both of the cell managers that I use. Eventually the entire server grinds to a halt and requires the RDS service restarting.
Both cell managers are DP7.01, Win2K8R2 with 32GB RAM. They have both been upgrades from v6.11 and are patched up to the latest level for v7.01.
Can anyone tell me whether this is a known issue and if so, is there a fix?
I found a couple of lab cases that references this problem
This problem is well known for intensive data driven applications running on Windows Server Family operating systems.
The problem is in the behaviour of Microsoft Windows's "Dynamic Cache Service", but it is not clear if an adjustment should be made to "Dynamic Cache Service" or to Data Protector's setting of an option that "Dynamic Cache Service" uses. Possibly both are needed.
Regarding Windows "Dynamic Cache Service", I read: SUPPORT COMMUNICATION - CUSTOMER ADVISORY Document ID: c03117812 Version: 1 CUSTOMER ADVISORY: Configuring the cache usage on Windows 2008 R2 system
as well as MS articles and blogs and forums and QuIXy cases about Windows "Dynamic Cache Service".
