Newer Linux VM's grow memory dynamically, and do not start with any explicity memory limit.
There are two command-line options (with equivalent environment variables) to control how memory is allocated on Unix:
If no options are given then memory is allocated dynamically with the limit set at 75% of the available virtual memory.
If -memory N{mk} is given then memory is allocated statically; the argument to the option defines a hard upper limit.
If -mmap N{mk} is given then memory is allocated dynamically, with an explicit upper limit to the amount of memory that will be allocated (but the "75% of available virtual memory" limit still applies).
