If you have no swap things will get killed, be it apache, a database, or
something else. The system won't go down if it runs out of memory. If the
system hangs it implies (to me) that it's a filesystem or kernel problem.
What filesystem are you running? Any RAID/LVM? Are you using EBS or is this
the local instance storage?

So rebooting via the AWS console/tools doesn't help? Note that it can easily
take 5 minutes or longer to reboot an instance via the AWS restart command.
After your instance has rebooted, there may be something informative (about
the problem) in the EC2 console output.
