I get this message in a file where I am using many external figures: error on line 1 in file chapter2.tex: ! TeX capacity exceeded, sorry [input stack size=10000] The wiki says: In texmf.cnf fix the value that has been reported as too small... In texmf.cnf I raised this parameter from 5000 to 15000: stack_size = 5000 % simultaneous input sources But got the same message. Any hints? Do I need to reboot something to make this new size be in effect? Do I need to reduce the size of some of my external figures? do I need to split the output pdf file into multiples?
