[THIN] Why session process very so much between users (and servers)

I am trying to identify any problems with servers we have (they are
pretty heavily loaded) and came across something that I can't explain.

There are a few processes that seem to use very different amounts of
memory between users and servers.

We have w2k3 sp2, CMPS 3.0 (3, with 2005.04 applied but ps4 not
selected).

Here are the processes I am wondering about and examples of users 

Server  who             ccapp   csrss   explorer        ssonsvr
taskmgr wfshell         winlogon
S1      doug_s          7092    5444    26180           2944
6516            6920            5824
        Doug_x  7120    5548    19004           2940            2460
6916            4028
                                                                
S2      doug_s          6728    5612    25888           2536
3184            6540            3772

I think I can explain explorer but the size of ntuser.dat (and whatever
it contains).  But the others I have no idea.
With 70+ users this sort of unexplained variance is tough to anticipate.
What is even weirder is that the memory usage seems to change ,
sometimes quite substantially, if I just sit there, which I did not
expect for some of these.


Server  who             ccapp   csrss   explorer        ssonsvr
taskmgr wfshell         winlogon
S1      doug_s          7092    5444    26180           2944
6516            6920            5824
        Doug_s (10min)5140      3868    19220           1936
