FATAL ERROR: Low global exclusion count!

Dear all, I was tring to do a sterred residue-based coarse grained
simulation of a very small protein 1AJJ, but got the following error
before the the first step of the simulation:

   FATAL ERROR: Low global exclusion count! System unstable or
   pairlistdist or cutoff too small

There actually is a thread in this maillist on a similar problem years


but no final solution was given unfortunately. I am attaching the pdb,
psf, and ref files here, and the info below produced following this


might be helpful too if anyone would want to help with this.

Many thanks!
