gsn_csm_contour_map problem

Hi There,
the gsn_csm_contour_map reports a strange error for me:

fatal:ContourPlotDraw: CPCLAM/AREDAM - UNABLE TO INSERT NODE INTO MAP
fatal:ContourPlotDraw: draw error
warning:WorkstationDeactivate: workstation not active or not opened

a simpler version of the code is:

tc  = wrf_user_getvar(a,"tc",t)
 lat = wrf_user_getvar(a,"lat",0)
 lon = wrf_user_getvar(a,"lon",0)
 tc@lat2d=lat
 tc@lon2d=lon
;;start plotting
 wks = gsn_open_wks("x11","Temp_1k") ;

 res = True
 res@cnFillOn       = True
 WRF_map_c(a,res,0)
 plot =gsn_csm_contour_map(wks,tc(10,:,:),res)

and the output from print(tc) :

some idea how can i solve the problem? is it the variable size? the same code with smaller variables work fine.

Regards,
Ico
