Um, what the heck is going on, all these recent threads have no topic post things... I've noticed the forum has been slow, whats going on? (sorry for ot, but this is relevant)
I'm running FTB DireWolf 20 on Far, Fancy, and with a 128x TP (with Optifine installed). I get about 60FPS on average, but after I've been playing a while, I get lag spikes every 10 seconds or so that last about 1 second each where I only get 2-3FPS. After the spike it goes back to the normal 60. I watched the memory usage in the F3 window and this is what I found:
I have 1GB allocated to the game (as was the default). When I first start playing, the minimum memory usage is 20%, max 50%. Starts at 20, climbs to 50 over a period of about 10 seconds, then returns to 20. Eventually the min will be 30%, max 60%, with the same climbing/falling action as before. The min/max numbers keep going up in this fashion, and I only start getting lag spikes when the minimum memory usage is 70-80%. It will climb from 70/80% as before until it reaches 99%, which is when the lag spike happens. After about a second the lag spike is over and memory usage goes back to 70-80%.
Anyway, I believe this is caused by a Java memory leak, is it not? I'm running Java 7 64-bit with an FX-6300, an HIS 7870, and 8GB of 1866MHz RAM. How would I go about fixing this?

No.
That's java's garbage collection kicking in. Hence why it spikes, then stabilizes. Try allocating more / less RAM.
Tried allocating 512MB, got a "run out of memory" error when I tried loading a world. I'm trying 1.5GB, I'll come back when I've been playing long enough.

If you remember, I said I was running so much at once in my FTB game, I need 3 GB.
I had 4 quarries and an auto processing facility in one mystcraft world.
Two areas chunk loaded in the overworld.
A mystcraft world dedicated to linking books and transportation.
I needed 3 GB of RAM allocated.
Lol. On a Technic creative world I built a massive Logistics Pipes auto crafting system/auto sorting system. Did this on my Dell laptop on Fast, Normal and with a 64x TP. I only had 512MB allocated and I pulled it off with about 30FPS xD
Anyway, back on topic, 1.5GB seems to be working. The RAM usage seems to be steadily hovering around 50%.
I am having the same problem, I had been playing direwolfs fine for weeks but made a new world using Mindcrack with the addition of Mystcraft and EE3. Got the same lag spikes from 70 fps to 0 every couple of seconds. I had no complex machines running, in fact had just started the world. Game crashes too after the lag starts. I had originally allocated 2.5g for ram and got out of RAM errors which is weird bc my world had nothing running. I then unistalled Mystcraft and still got it. Now I have traveled far away from my base and am still lagging and crashing just loading new chunks. I think it is caused by a new update to the FTB launcher bc it went from fine to sucky after the new version for the launcher not the pack came out. Also getting out of memory errors too. Looks like something is requesting tons of memory for no reason.

Interesting. Personally I do not use the FTB launcher to run the game. I download the mod pack. Then custom make a minecraft.jar with Forge and Optifine. From there I just treat it as a normal large modded Minecraft.
I do have latest Direwolf V4 to say, no ram issues at all and it uses 1GB allocation for now.
Myst craft is enabled, but I absolute do not travel to ages or nothing.
Just thought to throw that in.
Also I have a lot of machines and farms running, a giant castle, etc.

If you remember, I said I was running so much at once in my FTB game, I need 3 GB.

Where did you say that? If you're talking about the first thread I made, I went to bed right after I posted that and couldn't find it when I woke up.
Oh.

@ the first few posts
Anyway, as a few of us said, look into mystcraft as it is known to cause memory issues.
It's a shame there isn't any half decent forum software out there. IPB's the lesser of the evils.
You could go totally overkill and allocate 4GB or something.
Running the Mindcrack v7 with Mystcraft added doesn't have a memory leak issue but I was able to get up to 2.4gb of memory usage.

Mystcraft has a known memory leak, so I'd say you still have one.
Though, I still recommend allocating a larger amount of RAM than you have, OP.
