Update:

I looked at the server some time after two users had logged out and taskmgr shows 81% in use with FBserver dropping to:

Commit: 185kb
Working: 143kb
Private: 139kb

So it looks like there is a problem for me to find, although as the gstats output seems ok this is not going to be so easy...

This is the first FB 64bit app that I have deployed so if anyone has any useful insights as to whether you think the problem lies with the app or FB or a.n.other scenario then great. (BTW, the server is looking for a reboot following significant updates + symantec mail security for exchange has 10+ instances running on the server).
