Hi,  
I suggest:

- check your starting structure by looking at atom 4698, maybe some error occur when you built the starting structure and you have two overlapping atoms
- maybe you have one solvent molecule overlapping with another molecule, in that case remove it
- check the energy minimisation parameter in mdp file maybe some values are not suitable for your case (e.i maybe step value is too large)

Kind regards
