Monster 1.0.3 Concurrent Modification Exception

[Raptorana]

I am getting a constant 'ConcurrentModificationException' with Monster 1.0.3.

There is no crash, so no crash report, but the game is starting to feel like I'm running through treacle (Slow changing direction, slow to respond). This is near my base.

I am running on MultiMC5. I also have morph enabled.

Base has a Smeltery, Chunk loader, 160 JABBA Barrels and started just after I dug a 3x3 tunnel (for a railway) off towards a new base I'm building.

Console error below.

If you've figured out what it was, I could really use an answer. Actually the just about the same thing happened to me after digging a 3x3 tunnel gathering dark iron ore at bedrock level. I also added morph, but removed it and still had the issue. I also have a smeltery, 3 Jabba barrels, and a chunk loader. So far removing the chunk loaders, enderthermic pump, jabba barrels, and removing morph has done nothing to fix it.

Same issues with my Monster server, this same error occurs at least once every 5 minutes. Many times the error just constantly spams the console.

You need to post the full logs not parts of it. Also use pastebin for the log. Do not post Walls of Text.

Or not, because the issue is "known" and there are 50 other examples if you really need the full log. One glance through the forums would have told you that.

 

[Eyamaz]

Known issue. Unknown cause.

Known issue. Unknown cause.

There are a few fixes out though.. if you want to call them fixes.. One is simply removing all endertanks and liquid tesseracts. That worked for me, but I didn't find it worth it. Another couple people said it was problems with the Dragon API and it worked for them to update it to the latest.

 

[Eyamaz]

Yes. The one from DragonAPI is fixed. There are still others.
