Hi, I get the same error, but the information written in my log file is as :
Energies (kJ/mol) U-B Proper Dih. Improper Dih. CMAP Dih. LJ-14 8.26180e+04 5.53024e+04 6.50084e+02 -2.83474e+02 8.50267e+03 Coulomb-14 LJ (SR) Disper. corr.

Is it the problem which causes my system get this fatal error? I changed the pressure coupling to Berendsen and decrease the time step to 1fs. How would I be sure that my modifications is beneficial? By checking the pressure in log file passing the time? I would be appreciate you to help me. Thanks in advance.
