Sorry, that's not at all what the above link says. 

What Jinyun is asking to do is entirely within the NetCDF-3 spec:
a variable with an unlimited dimension is a 'record variable', and a
netcdf dataset can have many such record variables.

Jinyun has defined one 2d record variable and a second 3d record
variable.  This should be legal, if he has declared the dimensions and
variables correctly.  

Jinyun, you will not, for example, be able to re-use any of your
dimensions.  v1 and v2 will need distinct dimensions and variables.

Can you post your define-mode stanza?  Sounds like it should only be a
few lines long.
