I checked now some more WUs and the same problem existing. Running 2 Wus on my P4, HT enable and 150MB RAM usage, two big WUs had 300MB but 2 times more RAM usage in total is displayed. Anybody else have this problem?

WIN XP SP1, 2GB RAM, P4 3,2Ghz HT Socket478

I don't think there is a memory leak. I noticed the rosetta app reserves quite a big junk of virtual memory if it is available. On my machine with 1 GB RAM it reserved up to 430 MB RAM for some WUs. It never used more than 220MB but virtual memory is reserved. On average a WU reserves about 230 MB RAM and uses about 130 MB. However I noticed on machines with less RAM the same WU use less RAM and reserve less virtual memory. So I guess Rosetta grabs the RAM if availble but releases it if not available. That's quite ok I think. The task manager displays the total _reserved_ virtual memory so it is quite possible that Rosetta reserve for both instances 450 MB (900 MB total) for big WUs.

Right tralala. To monitor all this, I use the free ProcessExplorer util:

Btw, under Linux, memory use seems to be vastly reduced, not sure why...

A little bit confusing why the task manager didnt display the right values of Ram per WU?!

Why do you think it didn't? Have you enabled the column "Virtual memory"? Or based on which assupmtion you think the right values weren't displayed?

I have 1GB virtual memory but I mean the consumption of Ram for current WU.
