You might want to actually wait for all of those PS processes to finish before adding swap space.

It's not at all clear what "running as a background process executing every 60 seconds" means.

But your call to subprocess.Popen is forking a new process each time.

Update.

I'd guess that you're somehow leaving all those processes running or hung in a zombie state. However, the communicate method should clean up the spawned subprocesses.
