The NCL team has seen this, and reported it to the OPeNDAP folks --
this message is generated by the netCDF implementation that
resides within the OPeNDAP libraries.

Please rest assured that, after fairly extensive testing, data is
read correctly. This has been reported to the OPeNDAP folks, who
acknowledge that it's a bug and it will be fixed in reasonably short
order.

In the meantime, please be certain that the message you're seeing is
disconcerting, but NCL's behavior is not adversely affected.
Please contact me directly if you have any further questions or
comments. Thanks!
