Yes. but, it is true only when limit and guarantee are the same. Consider the following scenario: A system with 1024MB of memory. I want to create 6 classes: - 4 of which has guarantee of 128MB and limit of 512MB - 2 of which has guarantee of 256MB and limit of 768MB We cannot do this with this memrc. Can you explain how a userspace program can help me do this. thanks, chandra ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
