[gmx-users] Npt equilibration of the membrane-mimicking CCl4 layer

Dear Gromacs Users!
I have problems during npt equilibration of my solvent box with the CCl4
solvent (I'm preparing this hydrophobic layer for further
As the result I want to obtain density value ~ 1.5 for such box but between
2 and 3 ns ( where the desity was 1.3) of such simulation I've obtain error
One of the box vectors has become shorter than twice the cut-off length or
box_yy-|box_zy| or box_zz has become smaller than the cut-off.
1) What should I do in that case ? Should I use larger cutoofs ( I'm using
0.9 nm with the Gromos 56 parameters ) or extend some box vectors ?
2) Initially I've tried to use membrane mimicking dimensions 8.6 6.5
3.0 but during equilibration my box was shrinked to the 8.0 6.0 2.0
How I could present such shrinking ?
