91.0. "App requires lots more virt mem on 7.1" by COMICS::SHELLEY (Lead, follow, or get out the way) Mon Apr 28 1997 12:02

    Hi,
    
    I have a customer who has an application that appears to require
    more than twice the amount of virtual memory (pagefile twice as big)
    than it does on either 6.1 or 7.1 OpenVMS Alpha systems.
    
    At present I am waiting for more info from the customer but in the
    meantime I was just wondering if anyone could say if there are any
    known reasons for this. Generic comments are fine. I know the info so
    far is very vague. Thanks for your help.
    
    Regards

	The sysgen parameter IMGREG_PAGES will result in an increase in the virtual size of a process... It got quite the boost after 6.2. I don't remember if this impacts pagefile requirements though.
