hi, I am looking to control the size of the metafile on windows server 2008 r2. On the server I have been processing image files (about 10 million files) and have been noticing lately as the file count grew so did the utilized ram - even after I stop the applications dealing with the images, the utilized ram according to the task manager stood steady and even goes up with time. Through the RAMmap I found that it is the metafile that eats up the memory - to my surprise as I was suspicious of memory leaks caused by my custom applications. Does anyone have ideas on how to control the size of this file? I have turned off the HD indexing and while this somewhat slowed down the rate at which the file grows, it doesn't stop it entirely. My goal is to limit it to a fixed size as I am not really worried how fast the files are retrieved from the HD. Thanks in advance, Kiril

That links might help: http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/7b49424d-08c1-4fc4-bc9a-3569ab978efe The fix seem available only for Win2008, so a call to MS might be necessary...
