Your cellOrigin is set incorrectly in your .conf file. I measured this in
VMD:
measure center $sel
18.00963974 17.9956378937 17.9846000671
Try changing that and let us know if it fixes it or not.
As for the differences between Windows and Linux, both are numerical errors
so it's not so surprising really.

Subject: namd-l: Angle 2, Where is the problem [IMPORTANT]
I work as usual on my CO2 molecule bat i don't find the problem in my
simulation.
I have made too mach experiment bat i don't resolve the problem.
I wont made a CO2 solvent box, it is cubic and with 36A of side. In
this box there's 300 molecules.
I use packmol to generate it. To avoid problem with periodic boundary
conditions i generate a box 4A smaller.
The box start in {2.0 2.0 2.0} and end at {34.0 34.0 34.0}, the
tolerance is 4.5A between any molecule.
I generate correctly the psf. On this solvent box, I measure bounding
box that correspond with the input data of packmol.
>Main< (Desktop) 51 % measure minmax [atomselect top all]
{2.0 2.0 2.0} {34.0 34.0 34.0}
now i run the simulation on windows and namd plot out (below).
I run the simulation on linux end plot a different error!
Possible !?!?!?
I don't understend where is located the error.
