Your RAM having 1.2 GiB available does not actually indicate that RAM is tight. Much of the occupied space might be evictable files.
If you were truly short of RAM + swap, I think you would see OOM messages in the log.
I used to look at writes to the swap device as an indicator of how much I needed to reclaim memory. There will always be a certain amount but when it takes a step upwards at the time I added load, then I'm low on available memory. I have the numbers for Solaris around somewhere, but it was the sudden jump that tended to tip me off. --dave
