[gmx-users] Regarding No more replaceable solvent!

[Alex]

Please be kind to respond to the list and not to my email. I believe 
that 3-4 water molecules get removed per ion, depending on the insertion 
cutoff, so with 90 x 4, you're left in a situation where there's pretty 
much no water left. Gromacs is actually doing you a huge favor with this 
error, because it could manage to insert all the ions and you would end 
up simulating something nonsensical.

Increase your box size appropriately.
