Searched the forums here for a while to no avail but was able to find my answer on the web. For anyone as curious as I was as to what the numbers were on the bottom of "Running Services" in settings here ya go.
Finally, along the bottom of the screen are some obscure numbers. If you know how to interpret them, this gives you a lot of information on the memory status of your device:
* Avail: 38MB+114MB in 25 says that the device has 38MB of completely free (or likely used for unrequired caches) memory, and has another 114MB of available memory in 25 background processes it can kill at any time.
* Other: 32MB in 3 says that the device has 32MB of unavailable memory in 3 unkillable processes (that is, processes that are currently considered to be foreground and must be kept running)
There ya have it! Hope it was as helpful to some as it was to me.
