4 chunks with lag... (updated to standard format)

[cmc19]

Launcher/pack Version:2.1.0 with matching server

Operating System: Win 7 64 bit

Version of Java: 1.7 64 bit

Description of Problem:Whenever a player walks on to particular chunks they experience a 1/2 second of lag every 3 seconds. When they leave the the chunk the lag goes away altogether.

Error Messages:N/A

On my server I am having lag issues in 4 chunks, all right next to each other. 2 of the chunks are in our main automated warehouse. Whenever a player walks on to one of these chunks they experience a 1/2 second of lag every 3 seconds. Its extremely annoying. The strangest part is; the second you walk out of those chunks, the lag stops.

My first instinct was to shutoff the automated sorting system ( uses both buildcraft pipes and red power tubes). When we created the warehouse we made a master power switch, that would turn off every thing. So i flipped that switch... no change...

Then I started tearing things apart starting with the most recent additions to the system. eventually the warehouse consisted of nothing but walls , 40 - 60 chests, and torches... still no change. The lag was not any better or any worse.

Finally I took it to a technical level. I would stand in the the effected chunks, look at my F3 while doing a 'debug clock' in the server console. It returned "expected time elapsed 5000ms , actual time elapsed 5012ms". about a -0.25% error on average. Not a big deal. In fact it says the same thing when i'm not even in the simulation distance of the warehouse.

So now I don't know what to do... I'm just looking for some suggestions.

Re: 4 chunks with lag...

I know IC2 machine noises can lag out clients and that would be related to a small area as opposed to leaky items etc which would get you as soon as you wandered within 10 chunks (or whatever your view distance was set to). Try disabling IC2 machine sounds in your client's IC2 config (IIRC) and wandering in there. (assuming you have 1c2 machines in the area that is).

Since it certainly seems to be client side and the area doesn't seem all that graphics intensive it's about the only idea I can come up with.

I gave that a shot, no change. Its worth noting the second i leave chunk the lag stops. Also keep in mind at one point i ripped everything non vanilla out of the warehouse and still there was no change.

Thanks for the idea, i'm game for trying anything...

If your game for trying anything then perhaps delete those specific region files (mcr's) in the world's folder and let the chunk regen. If the lag is still there after that then something is corrupting those chunks.

If you got world edit you can even save your warehouse as a schematic and paste it in after the cunks regen. If the lag is gone when the chunk regens and then back again when you paste the warehouse back in, then you know its the warehouse causing it.

Also if you got world edit you can just try "//regen" ingame to regen the chunk. If that doesn't properly regen it then just delete the region file.

To get the region that your in (again with world edit) type "//chunkinfo" ingame it will tell you the exact .mcr file that your standing in.

I'm going to try that, i have confirmed that it is not the warehouse, i used world edit to do "set 0" to the entire chunk, and still it was lagging there (only bedrock present) and no where else. So then I decided to do a copy and paste (to remote location temporarily) . However, when pasting, only vanilla blocks pasted correctly.

Trying the schematic now. I will report back.

Thanks again

Update: same thing happens i lose all non vanilla blocks... (sorting components) is there a fix for this? If not this is probably what I will end up doing, but sure would be easier if I did not have to redo all the logic.

MC edit copy/pastes tekkit blocks just fine, I used it to save some creations of mine from a corrupted map. Its a stand alone application so make sure you work on a copy of the world.
