In addition to all the other great answers you already got: I've made it a principle to configure production systems with identical values for -Xms and -Xmx. In the end I'm intending to provide the max memory anyways, and if something goes wrong along the way (as it does for you in this situation) I prefer to know of the problems right when I start up the server - not Sunday night at 3am when it tries to allocate the missing (and allowed) chunk of memory from the OS before failing. Experimenting along this principle will help you to quickly figure out how much memory your system actually can provide (be aware of the required non-heap memory that Christopher mentioned, when forming your expectations.
