[FreeNX-kNX] Zombie hunting

[listen at kabelwelt-shop.de]

Hello,

I ran some fruther diagnostics for the previously reported login-problem
and found a huge number of "running" sessions. None of 'em is actually in
use, thus I decided to run nxserver --cleanup to purge 'em.
But this didn't work out quite well. I got error messages like

716 Terminating session CD21015A1413E6CBAB0AF560F32CD227 on user request.
rm: cannot remove
`/home/slauphi/.nx/C-epsilon.local-1029-CD21015A1413E6CBAB0AF560F32CD227//.nfs0066c72500000109':

or 716 Terminating session D22071AFF3B69FF49767FEE9BD3B7041 on user request.
rm: cannot remove `/tmp/.X1001-lock': Operation not permitted
rm: cannot remove `/tmp/.X11-unix/X1001': Operation not permitted

keeping sessions open...

What's wrong here? Can this be related to the described login-problems?
Furthermore, is there a way to automatically terminate all sessions being
inactive for - lets say 60 - minutes?

I'm using freenx v. 0.4.4-0a3sarge

Thanks in advance
Keep smiling
