Okay I followed the advice Booker gave and I had little stutter or slowdown on my SSP world. I did have a world leak in a dimension though..which is funny because on my SSP i haven't even been to the nether so yeah. I had to re enable the mods to play with my friend on his server and I got the stutter and slowness. Then it just crashed. I am not upset thought as I got a few things done and can affirm that those three mods cause a majority of problems but something else can cause world leaks. From the console it is Thaumcraft unloading aura nodes

Another idea....

If you can, jump into creative and place a chunk loader in each diminsion that is not unloading.... (I.E. the end, the nether, Twilight Forest, and any mystcraft ages that have been made...)

I was wondering, Could you attempt something for me?

  1. Disable all wirelessredstone addons.
  2. Disable mystcraft
  3. Disable twilight forests
  4. Leave everything else enabled
  5. Start a new world, in creative.
  6. Build, play etc... DO NOT go to the nether or the end.
    • Do you still get leaking worlds?
  7. Go to the nether, do / build / kill something
  8. Go back to the overworld
  9. Repeat step #5
    • Now do you get leaking worlds?
I have been having not the same issue, but almost. Seems we will have to wait for the modpacks to update. :)
BTG,

I will try to get this today. I am still on a business trip, so my ability to get to my PC and do this is somewhat limited.

Thanks,

I followed what booker said and it has helped immensely... I can now record my FTB Let's Play and also my FPS has gone back up to 70; it went down to 18.

Thank you Booker :D

Ash,

Not sure. I definitely updated to 1.7.0_15 when the problems began on the suggestion of someone else. It is possible that I may have both versions on the computer.

Here is the additional part of the pastebin after going to the Nether, killing a bunch of stuff, and coming back. Note that while I don't have a leaking world, there are signs that something isn't keeping up:

I also have this issue. its highly annoying. The simple semi-fix that worked was removing Wireless redstone and Any chicken chunks i had in my world. My minecrafts still gets memory leaks but i can play for much longer before it crashes.

Glad that it worked for you :)

PLEASE post your entire logs (both the console and crash-report) to pastebin, as it makes it much easier to help you.

Ok BTG, there is the final, complete log of the entire test you requested. While this last log shows a leaking world, my performance the entire time was pretty good. No stuttering for sure.

I followed your instructions to the letter except that I didn't have to disable Mystcraft as it isn't installed in Mindcrack. Test world for the second part of the test is btg2.

Hope that helps :)

Sadly theres no real crashlog that any of us can give since none of the mods have proper console log support to type out the issue yet.

well, new here on the forums (but not to mods glitching out and FTB/technic in general) but in previous versions if this has been persisting for ages on end I've never had a problem, but a few days ago it started up just like everyone else. I turn on for 10 minutes at best and get lag. Then gradually more lag, until about 10 minutes more and I'm down to freeze frames and then it either crashes with a permgen error of some kind or a general out of memory crash.

and you know what the moment was when it all started? When I tried to use buildcraft engines to extract stuff from barrels to and from a cargo manager connected to a wood farming cart I had going in my flatlands test world. Even the 5 turtle strong mob grinder I had already built using a nooby startup melee loop didn't cause terrible lag until of course the 10 or so brain jars ate all the EXP and the turtles got loaded full of loot and began leaving crap all over the place which is predictable.

Ever since said barrel lag out I've been getting the lag crashes. I've tried updating forge to the latest, optifine ultra 5, removing chickenchunks, updating chickenchunks and other possible world loading mods and still nothing. Sometimes I might get a fair game of half an hour before it starts acting up again but thats about it. All the time it's memory overloads or permgen space or something glitch.

Before that test that began my hunt for mod updates and attempted fixes I was I was able to have games of 3-4 hours long on my server with a buddy using my same pack ("my same pack" since it's mindcrack but with a few other additions I can't go without) ... Hell even the server crashed itself at one point when I tried to use barrels to store surplus materials so lets just say it's being a real douchenozzel and it seems to cause major problems when theres a certain mix of stuff going on. What that mix is though, I'm stumped.
