Can you post the command you are using and again how many input files are there and how many output files are being generated...as it is strange that nawk would complain about such a thing.

Code:
nawk: makes too many open files

looks like nawk stops after 20 files...
Close the file descriptor:
Code:
awk -F',' '{print> $NF; close($NF)}' file
