Since i have updatet some mods and Java to 7 my minecraft sucks and laggs every 5 Minutes for 1-3 seconds.

In my Log i found something that called: memory connection overburdened

Anyone know this? What can i do?

I have got a High end PC and Win7 Ultimate 64 Bit and Java7 64 Bit. I have also installed a Good amount of mods. But i changed nothing. And a few days earlier everything was okay.

Whats the Problem and how to fix it??

I am getting simlar probelms but I am lagging more than 1-3 seconds.
I am using MagicLauncher 1.0, Java 6 (down dated to 6 when I thought the issue was 7), and use rei's mini map, and optifine mods.  I run a creative off server and smp server.  I have attached my specs for my mac in blue, and the magic launcher information in red.

It's a RAM thing. The only way of fixing it (That I know of) is to completely bump up your specs. RAM and CPU are the parts to upgrade.

Thats a bit weird for me as I have upgraded from 4 to 8 GB of ram and the CPU is pretty fast for my mac.  I haven't had these problems before and I didn't think that mods were that memory hogish.

I have the same and find it hard to believe it's a ram problem since I get it on both my PC and my laptop however my circumstances are different as I'm getting it on a FTB modpack but yet don't get it on another modpack which uses some of the same mods. If it was the ram then you would be experiencing issues outside of Minecraft too and I for 1 am not, I did have some bad ram but recently replaced it with my currently installed 2x4GB ram sticks.

I think it's in the A.E. mod.

It only happens to me when A.E. specific blocks are spawned *and* placed in the world.  Rate of incidence increases roughly linearly with the number of recipes added to the A.E. crafting provider module (I'm testing with the minimum size, 3x3x3).  It also appears to trigger much more regularly with longer chains of crafting recipies;  I've tested with recipies for storage units since they're roughly 3N additive with respect to the number of constraints that have to be resolved to satisfy each successively higher recipie, ie: storage cell --> segment --> block --> cluster.  If I add one more layer, such as trying to autocraft a 64k storage unit (which requires a cluster, which requires 3 blocks, each of which requires three segments, etc., etc.) the failure is, so far, 100% repeatable.

Interestingly I've also noticed that failures with lower ranks of recipe "chaining" are usually not fatal, and that the longer the "chain" the more often they are fatal (ie., by locking up entirely or dropping mc into one fatal dump or another).

Also, from the system diags side of the fence:

- no memory bounding issues reported via strace (no alloc failures, no tremendous growth in segment footprint)
- no significant swap activity during any failures (swap activity delta across failure is less than 1%)
- no significant memory pressure at peak load or during any failures (max so far is ~2.2G, cap is 3G)

I'm gonna bet a coffee it's not a memory problem at all.

BTY the strace is just an 'strace -fFvp {task}' where {task} is the java launch with the session key already determined so that the strace can monitor MC rather than an MC launcher, ie.,



JAVAOPTS='-d64 -Xms1024m -Xmx2048m'

STRACE="{path to strace de jour}/strace -fFvp "

if [ ! -z "$1" ] ;then
    SESSION=$(/usr/bin/curl -s -d "user=$USERNAME" -d "password=$PASSWORD" -d "version=13" https://login.minecraft.net |/usr/bin/cut -d: -f4)
    if [ -r "$1/bin/minecraft.jar" ] ;then
    $STRACE /usr/bin/java $JAVAOPTS -Djava.library.path="$1/bin/natives/" -cp "$1/bin/*" "$MAINCLASS" # "$USERNAME" "$SESSION"
    /bin/echo "unable to find/read '$1/bin/minecraft.jar'"
    echo 'no minecraft build location specified'

Sorry, forgot -- drop the '-p' strace flag unless you're attaching to a pre-existing PID on a "sufficiently POSIX.2 compliant" platform.



Posted 16 June 2013 - 08:30 AM

Just throwing more ram at a client is rarely the fix for such problems. If you are not running with a 64x64 or higher texture pack, then you shouldn't need gigabytes of ram allocated for Minecraft.

I noticed a huge memory usage difference between 1.4.7 and 1.5.x With 1.5.2, I can't get a 32bit java minecraft client running well with a moderate modpack.
Up to MC 1.5 , you could easily run a heavily modded MC client using 32 bit java 7 with -Xms512mb -Xmx1gb. With graphics turned down to fast and rendering to normal and playing on server (so your client isn't generating the chunks), you could even combine it with a 32x32 texture pack. With 1.5.2 I haven't been able to do this yet without getting ridiculous lagspikes (with high fps). Memory usage keeps running against max memory.
My guess, 1.5.2 has a memory leak, which becomes more noticable if you are running mods.

u have to be wrong.
Today i made own pack with like 100 mods and everything worked fine. I launched game like 3 times no problem.
I restarted PC and game loads forever, and logs says exactly same as guy above. I've got 16gb of RAM and never experienced this problem. It just happened with no reason.

there must be bug with some mods

I just found this doing a google search for "memory connection overburdened minecraft"
@Muphet, you have to be wrong. I don't have any mods on my copy of Minecraft and this issue happens frequently for me. I haven't done as much research as others above, all I have done is increased the amount of memory available at launch and this delayed the onset of the problem, but after that initial delay the problem seems as frequent.
For me moving too quickly seems to make it happen more. For example if I flick the mouse for a rapid 180 degree turn, the game graphics slow to a crawl and the warning pops up in the log.
I think there's definitely some sort of memory management issue in more recent versions of minecraft, possibly an interaction between minecraft and lwjgl. It only started for me with more recent versions.



Posted 28 August 2013 - 08:27 PM

It looks like it might be mod problems with Forge. I think it was Chickenbones had a note at the top of his mod that said for 1.6.2 that you need to use scala-library.jar because of an error in Forge. I recently took that out of my mods folder and started getting this error. So maybe get that mod (on the Forge website maybe?) and that might help at least some of your problem.

I also have this prroblema with 1.6.4! mod I have a package of personnel and are about 65/70 mod and when I open the client every now and then gives me an error that says:

minecraft connenction overburdened, after processing 2500 packets, we still have to go!
Cant 'keep up! did the system time change or is the server overloaded?

I do not understand why it's so ... my old package had 91 mods on 1.5.2 and I have never had problems with 1.6.4 and has started to make me so ... I note that in less than 20 mod

as it does tell me that the server is overloaded when I'm opening the client minecraft? how you can solve?

I'm having this problem only in 1.6.4. This happens when I reach around 100 mods or so. It never happened before, in 1.5.2, I was using over 320 mods and it was fine... -_-
I too have a fairly decent PC.
