Further research shows that this is because 1.14.60 changed the protocol version - all other 1.14 releases have protocol version 389, but for some reason 1.14.60 has protocol version 390.

I can also confirm this does not affect Linux, only Windows - I ran my server on Linux first before another bug forced me to switch to Windows. On Linux I did not have this issue, on Windows I do.

My players on BDS are experiencing this as well, but with item frames containing items, not maps. We have approximately 200 item frames with items in a storage room, FPS drops whenever you look at it on xbox or the switch. Some players are experiencing it on PC as well, but not all.

This also happens when you lock crouch down by pressing shift+alt - you stop crouching when opening a chest or menu, and you have to double tap shift to crouch again.

I've ran into this bug as well, running a world on the Windows version of Bedrock dedicated server.
I copied the world to my local machine, and noticed that when I load minecraft, before I load the local copy of the world, it is ~550mb. After I load it once, it jumps to ~850mb.

I was able to fix the issue by opening the world in MCCToolchest, and deleting a bunch of regions on the outskirts of our world that we weren't using.
I've uploaded the corrupted world here:

I use Windows 10 Pro - I wanted to run it on Linux, but hit this bug: BDS-2574

My machine is currently broken and being re-designed, but I'll see if I have an older backup somewhere. If not, I'll update when I have a working version to share.

I was talking with a friend about this issue though and we were theorizing - maybe the server software is doing what it's supposed to, and just not releasing memory since there's plenty? I need to test in a VM and limit the ram to like 2GB and see what it does when it hits that - does it start using swap space, or does it release the memory it shouldn't need?

I've taken a memory dump of the bedrock_server.exe process while it is using 4.5gb of memory. This is after turning my furnace machine off, and leaving the area to unload it, and logging out. No players were logged in while this was taken. I have one ticking area, but that is at 8000,8000 - nowhere near the area we play in. There are no plugins loaded on the server.
Server version is 1.14.30, running on Windows 10 Pro, on an Intel NUC with an i5 8259U and 32gb of memory.

I can add a world download as well if the devs want it, but I don't think this issue is related to my world, as memory usage goes up even when my furnace machine isn't running, just not by as much. The size of my machine just makes the issue much more apparent than it normally is.

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've done some more testing on this, and it seems that at least on my hardware, the Linux version is just not very good.

With the Nuc 815, with Ubuntu Server18.04, just standing around doing nothing has one core running at 50-95%, depending on the area. Our world does have a lot of entities, so I tested in a new empty world, and in that one it's still a 40% single core load doing nothing.

Switched to Windows 10 to test, and on that, the CPU load on a single core is at <20% when doing nothing, and only goes to like 40% when I go near one of the areas with lots of entities.
On top of that, the loading that happens when a player logs in or is flying to a new area is much quicker, and only uses a few cores at 70-90% instead of all 8 at 100%.

Actually, it's even lower than that - 40% is only when loading and creating new chunks with one player. If it's loading existing chunks, it really doesn't get above 25%, and doing nothing but standing around it's at like 3%.
That's on my desktop, yet on the much more powerful server, just standing around runs at 60%.

The desktop with the 3470 is running Windows, the server is running Ubuntu Server 18.04.3
I think there may be an issue with the Linux version of the server.

I'm having the same issue - one user brings the cpu up to 60%, two makes it run at 100%, on a single core
I'm running an Intel Nuc 815, which has a i5 8259U
Testing on my much older desktop with an i5 3470, one user barely brings it up to 40%, and that's with running it on the same machine as my client - I'll test with other clients shortly.

I've ran across this issue in 1.14.20 as well

Experiencing this as well on xbox.
This also means that for players on a realm who haven't purchased the pack themselves, they have no way to make it work, since they can't change the setting.

I am having this issue in 1.14 as well. If I start the server on 19132 first, starting the one on 19134 doesn't try to use 19132, however, the server is not able to be connected to.

This really needs to be added back in to allow us to create server lobbies like you can in Java. No good reason for it to be removed, especially without mentioning it in the changelogs.

Bug MCPE-59035 is also open on this, it should be linked to this one.

Yup. Tried multiple strategies, leveling the beach, clearing all mobs, leading the turtles away before breeding. They return to their beach to lay eggs, but don't actually lay them.

Bug MCPE-59043 is also open on this.

I have this issue with powered rails. Regular rails can be placed next to each other, but powered rails cannot be placed next to each other in the North-South direction, only East-West

1.13.1, skeletons killed with a trident killer still don't drop anything but arrows and bones.

This is still an issue, and affects all Bedrock versions.
If you have no empty inventory slots, but have arrows in your off hand, you cannot pick up arrows and have them stack into your offhand.
