If you are using the file input instead of the command line and still hitting some limit, you can check if it is system open files limit [1]. On Linux, you can check soft limit with [2]: ulimit -a which gives 1024 on my system. And check also the hard limit with: ulimit -aH which gives 65536 on my system. And then increase the soft limit with: ulimit -n number Also, try it with some smaller amount of maps (like 10) to check that the issue is really in the open file limit (or command line length) not, for example, in the syntax.
