Practical Logistics 2 gives you the ability to create automated systems for reading, displaying and acting upon data. You can monitor items, energy, fluids, entities, machines, tanks, light, weather, direction, movement and much more. You can create Item, Fluid and Energy networks and transfer them anywhere in the world instantly; you can even transfer across dimensions. This mod also gives you more interactive control, via the use of Large Display Screens. This gives you infinite control and management of your base. You can also monitor and control blocks wirelessly.
The functionality is nice — really, really nice, even though it takes a bit of figuring out how to configure things — but doesn't always work as expected.
For example: Suppose you have a row of furnaces with inventory monitors on them, and they're side-by-side. Since there's no way to tell adjacent data conduits NOT to connect, they'll all be on the same "network". If you use the click-the-display functionality to put items into one of the furnaces, the items will not necessarily go into the inventory of the furnace whose inventory that display shows. It will instead go into the first furnace on the subnet that has space. This may thwart you if your intention was to drop one full stack (or even more so, half a stack) into each of the six furnaces.
More serious issues: There are sync problems when setting up displays, and displays frequently (nearly 50% of the time) fail to reconnect to their configured data sources after a restart and have to be reconfigured.
Most serious of all: I've determined that PL2 is not usable on an SMP server due to severe memory leaks, and eventually had to remove it and SonarCore from my 1.10.2 server, because after a couple of days uptime the server would be locked up and unresponsive, with CPU usage wedged at 200% or higher and unable to even shut down cleanly.
If any server leaks badly enough that you have to restart it daily, someone did something badly wrong.
If this one mod makes it leak that much memory, then I guess Ollie Landsdell should look into that.
Still, it is rather normal to auto-restart a dedicated Minecraft server daily (or even twice), even if it is Vanilla.
By the way, thank you for guiding me to this thread, person whom I follow. This mod looks interesting.
I've never had to do daily server restarts — but I suppose that's in part because I've never tolerated any mod that leaks memory that badly. I can count on the fingers of one hand the mods I've ever encountered that did so. I'm used to my servers running for weeks or months at a time without any intervention necessary.
I really hope Ollie can fix the memory and other issues with this mod, because it is astoundingly useful when it works.
