Added these:
% (Public domain.) % This texmf.cnf file should contain only your personal changes from the % original texmf.cnf (for example, as chosen in the installer). % % That is, if you need to make changes to texmf.cnf, put your custom % settings in this file, which is .../texlive/YYYY/texmf.cnf, rather than % the distributed file (which is .../texlive/YYYY/texmf-dist/web2c/texmf.cnf). % And include *only* your changed values, not a copy of the whole thing! % buf_size=9000000 pool_size=9000000 main_memory=8000000 save_size=1000000 max_strings = 5000000 strings_free = 1000000 hash_extra=10000000 stack_size=500000
