Hi!
        Increase vm.max_map_count limit in the sysctl.

from the docs:


"Specifically if you see the "Error in munmap" error on Linux you might want to increase the amount of maps available. Linux is limited to a maximum of 64k maps. Setting vm.max_map_count in sysctl.conf will enable you to increase this limit. You can inspect the number of maps your program is consuming by counting the lines in /proc/$PID/maps

This is a rather odd thing to document here - but hopefully Google will serve you this page if you ever encounter this error."
