Error_#IND in log file

Dear all,

Here with I have attached the log file for water (TIP3P) system.
The simulation stops with error saying out range atoms cannot compute pppm.
I have read the suggestions in lammps forum I read, but I could not figure out why it is showing #IND in log file.
Please help me out with this error.
Here the system is not subjected to minimization because fix shake is used during equilibration.

If you’re getting bad numerical results on step 0,

it typically means your input configuration of atoms

is bad. Bad input --> garbage output.
