Meaning of message - writing netCDF4 in long integer

Hi,

I am writing some grid in netCDF4 format (data type is int64 since I
want 12digit integer for data values)

It seems like my script writing without any problem and I do not see any
strange values in netCDF, but I am getting some kind of warning message:

file: NclNewFile.c, line: 5619
exists = 1

It would be great if anyone could tell me what this means...

A piece of NCL script is

+++++++++++++++++++++++++++++++++++++++
120 filhc12 = dirc+"HUC12/HUC12_"+reso(j-1)+"km.nc" ; the file has
huc array (type: int64)

126 fhc12 = addfile(filhc12, "r")

133 huc12_out =
fhc12->huc({24.512236:50.6875},{235.097796:293.9812530})
.....

144 setfileoption("nc","Format","NetCDF4")
146 ; Write all variable(s) to netCDF
148 dnam = dirc+"domain_conus_"+reso(j-1)+"k_bcsd.nc"
149 system("/bin/rm -f "+dnam)
150 fnew = addfile(dnam, "c")
151
152 ; Process 3 create global attributes of the file
153 cr = inttochar(10)
154 fAtt = True ; assign file attributes
155 fAtt@title = reso(j-1)+"km domain grid"
156 fAtt@source_file = filnm
157 fAtt@Conventions = "CF-1.0"
158 fAtt@creation_date = systemfunc ("date")
159 fileattdef( fnew, fAtt ) ; copy file attributes
160
161 fnew->x = x ; write to netCDF
162 fnew->y = y ; write to netCDF
163 fnew->ele = ELE
169 fnew->huc12 = huc12_out
++++++++++++++++++++++++++++++++++++++++++++++++++++
