Those numbers are practically meaningless. It could be any other
process.

The difference here is just 4 kb. Just an extra allocation of a page.
This could be from one random call. One extra process. 

To get more useful data:

1. Sample the data more often. e.g.: once an hour, with a script.

2. Build Asterisk with memory allocaiton debugging (requires enabling
dev mode, and has an overhead). This will allow you to see which part in
Asterisk (and even: which exact call of malloc) is respossible for the
constantly-increasing memory.
