So I'm not sure if i did the update right but players of the servers on both of the latest updates appear to be having issues with chunks loading it. My view distance is set to 8 and for some players its almost as if the view distance is at 1.

When updating the server do i just copy over the replaced files or do i use the installer again?

I found that the best way to update server was to download a copy of the world file.

• Download the update server pack from our server using sftp.
• Unpack update server pack to folder.
• Run the installer file and set it to the folder the update server pack is in (and tell it yes, I know there's stuff there).
• It completes installing, then edit the Java arguments file [user_jvm_args.txt] with the -Xmx command and I throw in the max amount of RAM I'm enabling our server to run at there (for our use, we're using 12Gb) so it's: -Xmx12G
• Save file.
• Copy the downloaded /world folder from server backup to this folder.
• Run the Run.BAT file.
• Wait for this to complete as far as it's going to go, and generate the file: eula.txt
• Edit the eula.txt file to 'true' to accept the eula, and save the file.
• Run the run.bat file again, and wait for it to fully spool up a server instance and the command line interface starts, it shows 100% world initialization.
• Wait a minute to ensure it's fully done loading.
• Type in command to command line: "/stop" and press enter.
• Wait for server instance to stop completely.
• Log back into our server via sftp and make a new folder called "update file version# to file version #" (i..e: ATM7_0.4.17_-_update_to_0.4.18" or whatever version you're going from and to).
• Use sftp command to MOVE the all the server folders and files on the server to the new server folder you created.
• Wait for confirmation they have moved, and do not exist in the main server folder anymore.
• Upload the full local server folder to server.
• Once this has uploaded, I select the new folder (minus the \world file, b/c I already have that downloaded earlier) for download for full local backup.
• Login to our server webpanel and start the server.

alright so I'm just going to remake the server files and import the world then, is there anything i need to be aware of when doing this? is there a process that the server needs to go through when an update is done or a world import has happened?

also I'm hosting this server from a personal machine.

Alright we found the issue, we had a person using the rainbow furnace and there were either to many effects or something else. We needed to use a world editor and remove the chunks the person had this the furnace on in order for it work properly. It got so bad we couldnt even go to the persons base in single player.

Maybe a memory leak or the fact that the particles continuously were loading, we are leaning to memory leak due to the impact on the servers tics and such but cant be to sure.
