What do you mean by "locked"?  Unresponsive to mouse or keyboard activity?
Blue screen?  What is your application doing while it's filling up memory?
Which memory, disk or RAM?

    rod> Is there a way to detect when the system is locked? 

Perhaps Nagios can help: <http://www.nagios.org/>.  In general, I don't
think a system can be relied upon to detect its own demise, as the recent
PC/Mac commercial about restarting illustrates:
