Please minimise the system for more duration., it seems that your system is not enough minimised

FATAL ERROR: Low global exclusion count! (92292 vs 92346) System unstable or pairlistdist or cutoff too small.
In my configuration file cutoff is 12 and pairlistdist is 14.
My system contains protein urea choline-o-sulfate and water.total there is 50712 atoms.Box volume 100*100*100.
please give me some guidance about it.
