[netCDF #QEH-836904]: Error initializing for parallel access

Hi Tim,

No, there is no such limit.

Unfortunately, your C code is not enough to reproduce the problem for 
debugging.  We
would also need an input file, or at least some characterization of how long 
the input
lines can be.  Can you write a small C program to create a test input file that 
shows the 
error.  Probably every line could be the same length, but we have no idea what 
that length
should be ...
