The problem is with the density of water .

You can use the below one

&SPECIES
!TIP3P water
DENSITY=55.296d0, !very close to 0.0333 1/A3 (very close to the bulk water
density)
MODEL="../../../dat/rism1d/model/T3P.mdl"
/
I have tried your script with nr=16384, dr=0.025 along with this density
modification given above then the script is running without any errors.
