Bad global exclusion count

Dear NAMD- users!

I was trying to run simple namd run for my homology-modelled protein which
is quite big in size.
It's PBC dimensions are like this (after solvating with option -t 5):

# Periodic Boundary Conditions
cellBasisVector1 105. 0. 0.
cellBasisVector2 0. 121. 0.
cellBasisVector3 0. 0. 125.
cellOrigin 21. 73. 27.
PME GRID DIMENSIONS 108 128 128

But I get the following error:
Warning: Bad global exclusion count, possible error!
Warning: Increasing cutoff during minimization may avoid this.

I increased cutoff values along with the pairlist-distance, but no impact of
them on avoiding this error. (Is there any rule of thumb to calculate cutoff
values depending on the PBC and PME dimensions?)

I read other posts with the same subject, but couldn't get the relevant
solution, so thought to raise this question again.

Looking forward for your valuable suggestions..

Thanking you,
Y.
