linux - Free memory is occupied

Question

I have the free memory getting filled up pretty fast, It seems like the ec2-user is running a script and the process moves to the sleep state and starts to occupy memory but never frees up.

              total        used        free      shared  buff/cache   available
Mem:           7.5G        6.6G        645M        9.9M        288M        683M
Low:           7.5G        6.9G        645M
High:            0B          0B          0B
Swap:            0B          0B          0B

this is the current free memory i have, when i ran the ps-aux --sort -pmem to check the process occupying the memory i could see

this is repeatedly occupying and i'm not sure if i should kill them or do anything else. As per my understanding if the script is successful it should free up the memory space but does this mean the script runs but fails to complete and moves into sleep state. And the free memory keeps increasing gradually. I'm new to this, So any help would be very much useful.
