Yes, that was certainly a problem. After issuing the command: echo 131072 > /proc/sys/vm/max_map_count to increase the maximum memory owned by a process to 512 M, the vm started correctly with 256M. However, the problem reproduces again around 310 M with the same behaviour. With even bigger sizes (500M) I get a different error (CONFIG_HIGHMEM not enabled).
