ERROR Message in Charmm

["Xiang(Simon) Wang" <simwang %-% at %-% chem.ufl.edu>]

Dear CCLers:
 I got the following error message when reading a protein structure
 solvated by a water droplet model:
 ****  ERROR  **** A COUNTER VARIABLE HAS EXCEEDED ITS MAXIMUM ALLOWABLE
 VALUE.
 EXECUTION WILL BE TERMINATED.
 THE CURRENT COUNTER VARIABLES AND THEIR MAXIMUM ALLOWED VALUES ARE:
 NSEG = 5 MAXSEG = 1000 NATOM = 42454 MAXA = 25140 NBOND = 42520 MAXB =
 25140
 NTHETA = 25666 MAXT = 25140 NPHI = 20579 MAXP = 50280 NIMPHI = 1333 MAXIMP
 = 9200
 NNB = 0 MAXNB = 17200 NDON = 896 MAXPAD = 8160 NACC = 12322 MAXPAD = 8160
 NRES = 12062 MAXRES = 14000 NATC = 193 MAXATC = 500 NCB = 225 MAXCB = 1500
 NCT = 554 MAXCT = 15500 NCP = 662 MAXCP = 3000 NCI = 65 MAXCI = 600
 NCH = 0 MAXCH = 3200 NCN = 5565 MAXCN = 20000
 I notice that the number of atoms and bonds has exceeded the maximum
 limit. Does it mean I reach the calculation capacity of Charmm?
 Any advices and suggestions are highly appreciated.
