Problem "Side: 2" spammed in console

[Piratkopia13]

• What OS are you running? Windows 7
• Are you using minecraft hosting provider or a dedicated/local server not designed for minecraft? Local server
• What version of FTB are you using? (Dont just say latest tell us the version) Unleashed v.1.1.2 & MCPC-Plus 636
• Did you add any mods to the server pack? No, just enabled some that are disabled from default
• What are your server specs? i5 2500k @ 4.5ghz, 24gb ram
• A good detailed paragraph about the problem

Suddenly the console log started to get the message "Side: 2" about 10-30 times a second and the server TPS dropped to 15 and everything started to lag badly.
We have tried removing chunkloaders in all areas to unload and locate the problem, this did not work. I've also temporarily removed applied energistics, logistic pipes and portal gun but none of them seem to cause it.
It did happen right when the AutoSaveWorld plugin was taking a backup, not sure if this have anything to do with it.
This is the second time this have happend on our server, as we couldn't locate the problem we rolled the map back when it occured the first time.

​

Plugins on the server:​

• AutoSaveWorld
• Buycraft
• Essentials
• EssentialsGroupManager
• LogBlock
• PurpleIRC

We would really appreciate any help on this problem, thanks in advance!

After a bunch of debugging and mod removing to locate the problem I have found the source of the problem, it's dartcraft.
I'll write another post if I find a fix without removing the mod.

Any clue what item in dartcraft.

I have contacted bluedart about it and he said that he might have left something in for testing with the Magnet glove in version 0.1.19, we were running 0.1.18 so im not sure if that was our problem. I'll come back if bluedart responds with something else after a second message to him.

Same problem here, except Side 5. It spams an entire screen's worth every 2 seconds.
Unleashed 1.1.3, MCPC+ b638


Edit: One of my players logged off and it stopped. I'll have to investigate what he's got...

Edit 2: He had a force infuser next to a pulverizer. The pulverizer was trying to send items to the force infuser.
