ARSCAM/ARPRAM - ALGORITHM FAILURE

Dear All,

I get the following error when creating a Latitude Longitude plot of
precipitation with gsn_csm_contour_map

fatal:ContourPlotDraw: ARSCAM/ARPRAM - ALGORITHM FAILURE
fatal:ContourPlotDraw: draw error

Please help to interpret this error message. We examined the data
separately using other browsing software and using ncdump but cannot
find any obvious problems.

One interesting observation is that if we add a small value to the
variable to be plotted, say variable=variable+0.01, the plot comes
out fine.

Any tips would be appreciated. (running NCL version 4.3.0)
