MC-105460Server CPU usage is extremely high when using GUI, even when no players are connected
Awaiting Response
started playing on a new world and there was a lot of tick lag
Did you wait a moment? everything needs to be generated, populated, etc, and that takes time.
Claudio Tinnirello Please create a separate issue with your findings.
I just updated my daughter's iPad to iOS 9.1 (to match my own iPad) and we see this same bug. We are also both running PE 0.12.3 Alpha.
LAN was working before we updated to iOS 9.1.
Seems to be the 1.10.1 client that has the bug. (Mac in my case).
I upgraded my server to 1.10.1 (from 1.10) and still get this crash on the client. No errors appear on the server.
Setting my client Profile to 1.10 (Minecraft Launcher -> Edit Profile -> Use version) lets me log into the server with no problems.
Setting the client Profile back to "use latest version" (i.e. 1.10.1) and reconnecting to my server causes the crash.
Now there's a popup saying "If you were trying to play on a multiplayer server, please contact the server administrators." That's not much help, seeing as it's nothing to do with the server.
Or are server admins expected to search the world for every sticky piston manually?!? :o)
Confirmed fixed for me in 1.10.2 on Mac. Great job guys!
I see the same issue on my Mac Mini. I've been running three minecraft servers on it for the last few months concurrently. Since updating to 1.10 (currently 1.10.1) the CPU usage has sky rocketed and I can no longer run all three concurrently. Going by memory, the CPU usage seems to have roughly doubled.
Upgrading my server to 1.10.2 made no difference. Killing all entities, except players, didn't help either.
I always run with the GUI (call me old fashioned) so, just for fun, I added the "nogui" option to the startup commend and... all my CPU issues went away.
My server was using ~200% CPU (I have a multi-core machine) with no players connected when using the GUI, but went to >1% CPU when I added the "nogui" option. Running all three servers now with no issues.
So my guess is that the CPU hogging is happening in the java Server GUI, although why 1.10 made it worse is still a mystery.
Ha! If you look at that other ticket then you'll see that I was instructed to open this new ticket!
Can you check with your colleague FVbiko (https://bugs.mojang.com/secure/ViewProfile.jspa?name=FVbico) and find out why they thought that mine was a separate issue?
Thanks.
I don't know about wget but there's a workaround for curl...
It seems that the server download page is checking that the request is being made by a "known" web browser so you can set the "user-agent" Header to make curl look like a specific web browser.
For example, to make the curl request look like it's coming from a Chrome browser on Mac you can specify the curl option:
-H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)'
I hope that posting this workaround here doesn't incite Mojang to further restrict access to the download page!
