Title: Tekkit has lag spikes and crashes after 2 minutes

Version: 3.1.3

OS: Windows 7 Home Premuim, 64 bit

Java Version: 1.7.0_09, Oracle Corporation, 32 bit

Description of Problem:

Whenever I go into Tekkit, it lags a lot sometimes. I only get to play for about 2 minutes before it crashes by not responding and I would have to Task manager and end the task.

That's not very helpful. If you want this fixed, you need to give us more info, like error logs for instance. The only thing I can think of from what you've given me is that you haven't allocated enough RAM, to either your launcher, or your server, or both.For adding more RAM to the Technic Launcher, load it up, and before you click 'Login' click the 'Options' button below it. Then select the memory allocation amount from the drop down bar. 2 GB should be enough.

Adding more RAM to a server is more complicated. Go to the server folder, and instead of left clicking 'launch.bat' to start the server, right click it, and select Edit. If a prompt comes up asking you what programme to open the file with, select Notepad. There should be two lines of text, looking like this:

java -Xmx3G -Xms2G -jar Tekkit.jar nogui

pause

Replace the '3' in the first line with 4. It should now look like this:

java -Xmx4G -Xms2G -jar Tekkit.jar nogui

pause

Save the file, then exit Notepad. The server should now have enough RAM to run properly, as should your Technic Launcher. It would be more helpful knowing what the exact problem is, but this is what I can think of off the top of head with the very little information you've given me.

You can also remove the nogui part. This makes the gui pop up, on the gui it's easier to read/copy errors. (Just a tip for any future errors)

There are no error logs. I have enough allocated RAM, but I only get the choice of 1GB. No, I don't have a server for Tekkit. Like it says, I only have 32-bit Java with a 64-bit operating system. I'll try to get 64-bit Java some other time. And the time collapse before crashing is like, 1 minute. Forgot to add this in, but it always deletes what I built before the crash and keeps what I built from 30 or more seconds ago. For example, I was building a rocket and I was building a coolant supply. I hooked everything up and then Tekkit crashed and when I logged back in, the only thing left was the coolant tank, the coolant supply, and some pipes leading to the coolant supply, unfinished.

I got it fixed! Yes, there is a 2GB setting, just Tekkit put it in KB, not in estimated GB. Still lagging, but hey, at least I get to play Tekkit.

Nope, not fixed, now worse. I can only play for about 30 minutes before crash.

Well, try and get the 64 bit Java ASAP, as that may be causing this. Also, back-up your world to another location, and delete your .techniclauncher folder, and your launcher (be on the safe side), then re-download and re-run it. There may be a problem with one of the mods, but this is hard to tell when its not on a server, as they are no bug reports. (When you re-run the launcher, make sure you allocate enough RAM again)

2 GB should be plenty of memory, unless you have craploads of background programmes/processes running simultaneously. Background programmes may seem innocent, but sometimes they really chew up your memory, leaving so little Tekkit struggles to work correctly. Remember, it has to keep track of so many more variables than vanilla Minecraft does. Bring up Task Manager and check memory usage. I will almost guarantee that there are loads of unnecessary programmes running. You can us Microsoft Management console to restrict which programmes run at which times, and which ones start when you boot up. These solutions should fix your problem.

I do have a lot of background, but they're all minor. Usually the top memory users are Tekkit and Mozilla Firefox. Tekkit takes up about 800,000 KB and Mozilla Firefox takes up about 200,000 KB. I won't need to backup my worlds since they're all useless (I didn't port my worlds from Minecraft to Tekkit). And what do you mean this is hard to tell when it's not on a server? You mean you want me to post my server conflicts, because I do have one.

If a mod is not working properly and conflicting with your world, it could be doing this, and a server prompt will tell you exactly what is up. These thing affect random players at random times. You could reinstall Tekkit, like I suggested, and start a new world. If this doesn't clear up your lag, its your computer that's causing the issues.

I got 64-bit Java, 7 10, and it doesn't crash and doesn't lag.
