We have a number of cloud servers and I am building a new one to test provision of resources on.
I am getting a fatal crash way before I think I ought to, as some sort of system resource is running out.

The operating system is Ubunut 8.04 (LTS) but our other ones are Ubuntu 9.04 and Ubuntu 9.10 - I think we will have to standardise them :(
So my questions are:
- how can I identify what resource is running out?
- what proactive monitoring steps can I take to ensure that it doesn't happen again?
- which system resources, in general, might I be able to exhaust with an Erlang VM, and what monitoring steps I should have in place for them?
