maybe i can help, what mods are you using?
using the ftb infinity 1.7 modpack, added to that forgeessentials, fastcraft updated, betterfps,stackie, specialai, just removed opis i was using it for finding cause of cpu but cpu is fine now kind off.
edit: great.. cpu usage is often at max now, and server is complaining about skipping ticks, but its flooding with the error msg as well so..
MaouKami: That's quite well reprducable indeed, I'll see about adding said debugging functionality.
Yeah, still having this problem, have no clue where its coming from, but do know its not fastcraft, ran it without i simply get the same message,
But without the 2 strings about fastcraft, but if you still think you can add a debug function so i can find what is causing it, that would be awesome.
Starting to get more and more problems atm haha, just had to add another 2gb to the server counting up to 10gb total, cause on startup its now using 5gb.
And within a few hours reached 8gb, while nothing has changed server-wise, and found no good tool to locate the spot, or mod that is causing this.
You would think it are loaded chunks but nope, not that many chunks loaded, even lowered the chunk loading limit.
But thats something all together :p.
Display MoreXee1: That's not related to FC, with 1.22-ctest10 it'll just show up in a lot of stack traces just like minecraft itself, but doesn't have much of an effect on the crashes themselves. Likely causes for the crash I can think of are:
- a potential race condition between placing a block and using an inventory which doesn't contain the hotbar slots, i.e. doing those at a very similar time
- broken mod code in a gui that allows placing blocks while it's open
- a mechanism that places blocks as if the player placed them
- a faulty mod edit to the ingame gui (the one showing just the hotbar as in no "machine type gui")
MaouKami: That's possible to debug with somewhat elaborate monitoring code, but that's only worth the effort if it happens frequently enough or can be reproduced easily. If it does we should get in touch to deploy that.
lil_kreen: What do you mean by "game menu"? The main menu or the one that shows when pressing esc while ingame? The latter stops the integrated server thread/processing while being shown and thus pauses the game.
As far as I'm aware such a large difference between ingame and paused may come primarily from lack of heap memory, saturation of all cpu cores or overly frequent chunk updates.
The debug screen can show some profiling information (http://minecraft.gamepedia.com/Debug_screen#Profiler_graph), yielding some more insight how much time is spent for entities/tile entities (root.gameRenderer.level.entities), chunk updates (root.gameRenderer.level.updatechunks), the actual world rendering (root.gameRenderer.level.terrain) or client-side simulation (root.tick). You have to re-open the debug screen to reset the values, otherwise they just accumulate+average infinitely.
Well is a 1gb+ log file enough times ?
Of course i cleaned it, cause the ssd is already filling with backups.
But yeah it happens way to often. If you have time to help me out a bit that would be great :).
Another question quickly while i am posting, could this also be the cause of the suddenly higher cpu usage then normally ?
Bogdan-G: The most stalls are server side when you do world edits. The client part looks fairly healty, there's only those suspicious glFinish calls, but I have no idea what's going on there. Maybe a mod renders too much geometry or forces lots of state changes in its block rendering code. The GC problems I've seen earlier are fixed. Unfortunately the sampling mechanism isn't very good for investigating spikes atm, so I can't really do anything more.
Entoarox: Thanks, I think I've just fixed this, did you increase the view distance by any chance? The issue is in FastCraft.
MaouKami: Tentatively that's not caused by Fastcraft. Apparently something adds/removes entities from a thread or an entity's writeToNBTOptional implementation does likewise.
Any way to find what mod is causing it ?
Hey my console is suddenly spammed by this msg,
http://pastebin.com/msy6r0VC using ctest10 :).
Not sure if related to fastcraft but otherwise i would not know what is.
Thanks in advance.
