Thanks Hamish for the explanation and the reference to where in the
code the limits are (were) kept.

Thanks Glynn for the move to to dynamically allocated history fields.

:-)

In answer to the length of the filenames I was using... they were too
long generally and I realised that I could avoid them. I was storing
model outputs which included parameters, time step, model names etc to
differentiate. Now I use separate mapsets for each specific
combination of parameters and just use a subdirectory in the mapset
for storing model metadata/analysis.

edit: I just looked up some model logs where I was having the issue
and the files causing the problems were 155 char long in a mapset 24
chars long.
