RuntimeError: NetCDF: Operation not allowed in define mode

What steps will reproduce the problem?
1. run the attached python script to see the exception (the exception also 
occurs when format='NETCDF3_64BIT')
2. Change(decrease) to 1000 the number of times stored in the netcdf file and 
the error will not occur.
3. with 10000 steps and format of the netcdf file 'NETCDF4_CLASSIC' the program 
works correctly

What is the expected output? What do you see instead?
Expect program to run without the exception.
Instead I see the following exception:

Traceback (most recent call last):
  File "test_nc4.py", line 29, in <module>
    latVariable[:] = lat2d
