Why do I get XDR error messages when trying to write data?

Probably due to a write error, perhaps because of exceeding disk quotas, a full device, or permission problems. The netCDF library is usually built on a vendor-supplied XDR library layer. Sometimes errors occur in the XDR layer rather than the netCDF layer, and in this case the error messages from the XDR layer can be cryptic. For example, if the user is writing data and exceeds a disk space quota, this might be detected first in the XDR layer. Although we try to catch and elaborate on errors that occur in the XDR layer, sometimes there is not enough information passed up to calling routines from the XDR layer to make construction of a meaningful error message possible.
