I got some wierd problems and i think its mekanism related and maybe something with Cofh since i see the ASM event handler inthere, It occurs every 6 to 12hours and it makes the server unplayable.

were running modsauce 1.0.1.0 and the problems were there in 1.0.0.6 too.

Here are the versions that i use.

1.0.1.0 - Mekanism-1.7.10-7.1.1.127
1.0.1.0 - CoFHCore-[1.7.10]3.0.0B8-36
1.0.1.0 - CoFHLib-[1.7.10]1.0.0B6-26
1.0.0.6 - Mekanism-1.7.10-7.1.1.127
1.0.0.6 - CoFHCore-[1.7.10]3.0.0B6-32
1.0.0.6 - CoFHLib-[1.7.10]1.0.0B6-26

the error itself, came back every 6 to 12 hours after a restart and ocurred every 10 - 20 secconds:

I hope some1 can help me with this would be nice! Thanks in advance!

Basically the same error I reported in #2060. Hope we get some word on that; looks like an outdated CoFH API in Mekanism.

What makes you think it has anything to do with CoFH API? It's a ConcurrentModificationException...
The ASM event handler is FML's and there is no CoFH API in Mekanism.
I think this is most likely us being sloppy in our HashSet usage - I'll see if I can get a build working that'll help me work out where this is being caused.

Meh, I've seen a report like this waaay back in 1.4.7, and Aidan said it was an API issue. I'm not a mod dev. Thanks for the debug jar.

Fair enough - API issues tend to manifest as errors about missing classes or missing methods, or sometimes about casts. Errors like NullPointerExceptions and ConcurrentModificationExceptions are usually just the developer (of whatever is throwing the error, in this case us) having made a mistake.

Here you go - replace your Mekanism.jar with this jar. It won't fix the problem but it'll hopefully provide more useful logs to help me fix the problem.

It's horrible spam. Mekanism 7.1.1

http://hastebin.com/ajifoxeraf.avrasm
http://hastebin.com/qeyuqokeho.avrasm

server have 20TPS with this spam, but players have lot of lags and kick with reason "time out"...

I tried MekanismDebug and it is little different, but same spam.

http://hastebin.com/qojolowuto.avrasm

It´s mekanism only or something else?

EDIT:
After update AE2 same error from mekanism :/

http://hastebin.com/facetegexu.avrasm

EDIT2:
Mekanism digitalminer
hastebin.com/sehijivedo.avrasm

Do i need to give more info or are we waiting for the mekanism dev to reply here?
My forum with some screens from what is happening the profile images are not verry accurate i can provide more specific profiler images:
http://zenixgo.enjin.com/forum/m/27460712/viewthread/17999365-modsauce-freeze-aka-lagg-spike-problem

I had some people complaining about lagg and dcs when using/setting up the digiminer.
and in the error i wonder what this means:
net.minecraft.block.BlockStaticLiquid.func_149674_a(BlockStaticLiquid.java:95)

Could it be something with un chunkloaded mekanism machines?

Thanks for thinking with me by the way! really appreciated!

for now we've written an auto restart script so my players can play without lagg however the log is still almost unreadable.

ive put the debug in and the server crashed as soon as some1 logged in, ive tested it 3times and its caused by the debug version, somehow its a ticking entity (buildcraft laser), then ive put the original mekanism in i can enter that area without crashing the server then ive put the debug in cant enter that area instant crash.
Heres the error:

I forgot that my IDE's build system confuses gradle... Redownloading it should fix that issue.

nobody can connect with the new version: error occured connection terminated

Well, it looks like what I was trying to do there didn't work at all. I'm going to try something that should stop the ConcurrentModificationExceptions but I worry that it'll just cause a deadlock. Weird stuff like this tends to be caused by chunk-thrashing so if you could try chunkloading the networks that are causing the issue and see if it goes away, that could be helpful. I'll see if I can get another debug build out and see how that works as well.

A full log with the last debug build could also be helpful, if you're able to send one.

booting up with the debug atm!

I've uploaded a new Debug version that attempts to fix the issue. If you get issues with nobody being able to connect again, pastebin a log and I'll see if I can work out what the problem is.

got the debug working now waiting for the error to appear!

now i can log on but it seems that the debug gives no errors

I guess it's fixed the CME then. I'll close this for now - if you have more issues with connection being terminated, open another issue for that, I think it's unrelated. Build server is down at the moment but these changes will be in the next build, whenever that's able to happen.

when i fly in specific areas i get : a fatal error has occured connection terminated.
When i relog i immeaditly get that message. No spammed log with that error yet.

without the debug version u made the errors show again.
Ty anyways for the help
