> What happens to the isolated Erlang processes when the VM fails to allocate more memory from the OS?
It suspends your process, then logs into newegg.com and buys more memory sticks for your sever. You know it is just a regular VM and doesn't have magic in it. If you use up all the memory on your server you are screwed probably.
You could set up a monitor to see which erlang process is eating memory and what rate and then decide what to do, kill the process, restart the whole node, or report someplace.
