You should generally equilibrate at constant volume first, and then turn
on constant pressure. I note that you density is very low, but maybe that
is what you expect here ("solvent box of monomers"). If not, check to see
what is going on.

The fact that such bad things happen on the first two steps may have nothing
to do with constant pressure. Be sure that the potential energy starts at the
same place it had at the end of the minimization.
