I may not post as much any more, but I do lurk around sometimes.
If I remember correctly, Threadmaster stopped being free for commercial use
at one point, so that should be pointed out.
As to the memory.
You can't place a limit (e.g.: WSRM quotas) on how much memory a process can
use without crashing apps.
What you can do is limit apps from needing as much. The RTO / Citrix
approach (or similar ideas used by Appsense, Tricerat, and others) reduces
memory usage by fixing up dlls. This has a much bigger impact on a
terminal server than it would a desktop or non-ts server, due to the greater
amount of dll sharing that happens on a multi-user system.
Also, another approach you may find out there are snake-oil memory saving
tricks that should be avoided. Generally, these tricks cause all currently
used memory in ram to get paged out to the page file in order to free up
ram. Really bad idea.

Jim K. introduced Process Lasso to the list a while back, which is also an
excellent utility for controlling CPU usage. The added functions of being
able to set a process's priority level, or CPU affinity has come in very
handy for us on a few occasions where we used Process Lasso to boost the CPU
utilization of specific EXEs.
It's default behavior is to cap CPU usage for processes when they reach 20%.

Unlike threadmaster (which I'm still a fan of), process lasso is still being
actively updated, and it's supports x64 systems.
Not sure of utilities for memory cap'ing exe's . . I vaguely recall some
registry modifications that could be set per exe on a system . . will see if
I can digg some of that up.

i'm not opposed to paying for something if it works. And you are correct,
threadmaster does nothing for memory. i"ll check out what appsense has.

Without wanting to do a sales pitch I don't believe Thread Master controls
physical memory. AppSense Performance Manager will control CPU and physical
memory for a process. It is however, not free of charge...
To be open, yes I do work for AppSense.
Thanks,
