Re: problem reading multiple netcdf files in ncl v 5.1.0

Not sure of the issue here. We read many more file than 30 or 60.

[1]
The "add_connect" is not familiar. Are you using a DODS
enabled NCL?

[2]
You could try setting "SuppressClose"
http://www.ncl.ucar.edu/Document/Functions/Built-in/setfileoption.shtml

setfileoption("nc", "SuppressClose", False)
