440 MB of usage in json.c and 3 GB in stasis_channels.c look suspicious.

Are you using the JSON_DECODE function by chance? There was a memory 
leak bug in it fixed a while back[1]. However, it was not cherry picked 
to the 16 branch as that was after 16 went out of regular support. So if 
you're using this function, you have a buggy version that is likely 
responsible for your leak. You can fix this by upgrading to a supported 
version of Asterisk.
