It looks like your system has many more nonbonded interactions than the
program is expecting. This suggests that something funny is going on (too
high a density? An unusual starting structure?)

You might try a preliminary vacuum or GB minimization to see if that suggests
anything. Did you do anything out of the ordinary in solvating the system?

You can increase the value of MAXPR in locmem.f, but it is probably a better
path to try to find out what is unusual about your system.

...good luck...dac
