RAM usage increased as players connect to the server which is normal. The RAM Doesn't drop free up after players disconnect. After 8 hours running, my RAM usage for my server is 277 MB. WHen the server is first started with no players, the usage is around 60MBs.

I'm seeing a similar issue. I created a very large furnace array that burns bamboo to smoke kelp. In total the system has over 140 pistons and nearly 200 blocks of sand that fall, and it creates 900 smoked kelp per minute, which gets put into water. When the machine is on, server memory increases by 6mb per minute, and it is not released when the machine is shut off, even after unloading the area or logging out entirely. RAM usage increased to 4.2gb after 8 hours running the machine.
Granted, this is with a massive machine, which is not typical, but looking at the memory usage of the process, I see it go up by a few KB every 10-20 seconds without the machine running, but I'm not seeing it go down, even with no one logged on.
(edit: To clarify, memory usage only goes up every 10-20 seconds while players are logged in. When players are not logged in, it does not increase, but it also does not decrease)

I'm going to temporarily close this one off as awaiting response. At the moment I've not seen any evidence of a memory leak and until we're able to pinpoint reproduction steps there's very little we can escalate to Mojang.
It would be expected that the server wouldn't always revert to the amount of memory it uses when its first started. Many entities etc remain cached for performance which increases passive memory usage. I run a bunch of servers and wouldn't consider the behaviour I'm seeing from BDS unusual.
Thats not to say there is no memory leak, just that, from what we have right now, there's nothing that can be escalated. If someone is able to find clear evidence and reproduction steps to demonstrate the issue please comment back and the report will reopen.
