uSkyBlock
This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.
uSkyBlock is an open-source Skyblock plugin for Paper and Spigot.
Start on a small floating island, build it into something thriving, complete challenges, and team up with other players to push your island further.

Why uSkyBlock

If you are still having issues with the lag spikes then mind telling how much ram your server is running on? and what your TPS is regularly? those may be the reason as to why you get lag spikes when breaking blocks.

@dutchy1001 I was wondering if it is possible to remove the bedrock in any way, either will letting the players somehow remove it or not have that specific type of block? With making an island some, is not all players, don't like having a random piece of bedrock on there island and having an admin go and remove them constantly can be a pain sometimes lol.

When a player joins an other player or when an island gets deleted with the command /usb island delete <player> the island will be delete and the location saved into the "orphan.yml", the next "new" player that creates an island will then get that location so empty spots are fulled up.
@Okxido
I'm sorry that I cant offer more help on the matter. Our main dev is having a few days off and wont be back till aftr the weekend. As said before that this most likely isnt an uSkyblock problem I dont think we can do much, special when other skyblock plugins have the same problem.

OOOOHHHHh *facepalm* I forgot to update worldedit >.< Everything else I updated but the one thing I forgot was worldedit lol, I decided to just make the server 1.8 as well with a protocolsupport for 1.7 users so went ahead and updated everything to 1.8 and forgot worldedit lol whoops. Well thanks! :D Also quick question, when an island is deleted or if a player leaves the island by joining someone else, that island gets wiped right? That way there isn't an island floating around randomly somewhere?

do you use a custom island?
Timings look fine to me but I'm no expert on that.

The timings command would not fix the issue, it's to see were the server lags on or has problems with. It shows the ticks from a "task" the server does and some experts can tell you then what needs to be looked at (that wont be me in this case lol).
It would have been easier just to post the link you got from the timings report and not made into a pastebin.
As you already said "i know have tried with some different skyblock plugins" it is not a problem that we can fix but a problem caused by something else, could be bukkit/spigot or maybe an other plugin.
If you could setup a test server with the basic plugins (permission plugin (any), uSkyblock, Worldedit, WorldGuard, Vault and Multiverse-Core(not a must but I would)) then test if the problem still occurs and report back would be great. For WE and WG I would use the latest dev builds as you can find on this page above.
If the problem isnt there then add 1 by 1 your other plugins till the problem occurs.

I tried /timing on but no effect, bukkit said "Timing (Reset/Merged)". But i have that when i have do reset, break block and "freeze" and /timing merged : ( http://pastebin.com/6DERFn1f )
@TehRealDeadman
Yeah i know have tried with some different skyblock plugins :( I started the server with Spigot 1.8.3 / CraftBukkit 1.8 and 1.8.3 but now the concern remains.

Thanks for clearing this up that it isnt a uSkyblock issue. With having the same in the other skyblock I already was sure it would be caused by something else.
About your Pastebin, it's caused by WorldEdit. When does this error happen? What versions are you using from WE and WG? As I see in the config make sure Vault is v1.4.1 .

This isnt with Skyblock, it has to do with minecraft/spigot/craftbukkit itself. I run a prison server and when a player breaks a block that is in mid air and nothing is under it then it can cause a lag spike. Has nothing to do with skyblock, idk the issue source or why it does that but I know it isn't skyblocks issue. lol Forgot to post the pastebin of the console error. here is the error in Console http://pastebin.com/H5PF7ewF I may have missed something obvious in the error but not sure.

Are you saying that this happens with ASkyBlock, IslandWorld, and uSkyblock, all the same bug??
Have you tried to make a "timings" report while the bug occuers? This can give a direction in which way to start looking. (command is "/timings on" then after "/timings paste" and post the link here)
@Cyborg20005
We (the dev team) have discussed this a long time ago but came to a dissension not to add as there are chat plugins out there that can do it.

Posted Apr 22, 2015Could you add a private skyblock chat? like for only the island leader and the island members to use? Possibly on the next update if possible?

Posted Apr 22, 2015Hi !
When a player breaks the block facing the void, the area containing the player undergoes a very big freeze (For example, if the island has two layer, the lowest layer that produces this freeze)
I have try ASkyBlock, IslandWorld, and uSkyblock, do new map 2-3 time per plugin. I tried with just Essentials, uSkyBlock, WorldEdit, WorldGuard, Vault (With Craftbukkit 1.8 and 1.8.3) And no error in console. :(
How to solve the problem ? :'(

you cant untill we compiled it into the plugin. You need to rename it to "pt-BR.po" (Portuguese (Brazil)) and fill in the fields as mentioned in the Localization page. Then upload it to pastebin and post the link to my pm box. I will then add it to the plugin for next release.
