Although you should make sure that opening so many file handles is absolutely necessary before resorting to such adjustments. Increasing the maximum file handles just because you have forgotten to do an inputstream.close() in a loop is only going to delay the underlying problem.

Answer 4

vi ~/.bashrc And add a line at the end of file

ulimit -n 169203
