Honestly I have no clue how but my server is reporting 3gb ram used but my actual process is using 19gb of ram

Does this mean there's a leak somewhere?

We've been having issues where the server would eventually start having extremely low TPS and eventually crashing, I'm guessing it's due to the fact that the server is literally using more and more memory until the entire system starts using swap and everything going bad
Also I literally have 16gigs allocated for the server in the JVM flag but it uses 19gigs?
I'm guessing this is a clear cut case of a memory leak, but no clue where

16 is whats allocated + either a native mem leak + overhead
