I'm getting a bunch of material with ID already exists type error on my server log:

http://pastebin.com/XHdkQ0af

Running Latest version with Cauldron 1.7.10 1492.155

Try not using Cauldron

That's a super smart remark. And just to be as smart as you are, I'll answer that I'm not using Cauldron.
Try to figure that one out.

Well, we could use the log without Cauldron in the set up.

I have over 150 mods and never had that type of error before I installed Chisel, going on a year and a half. Is there a way I can check those ID's?

Can we have the full log?

If we get the full log, we can determine what the problem is.

You never once said that you tried without Cauldron. You also never provided a log from without Cauldron.

And it wasn't a "super smart remark". It was him asking you to try without the unsupported hack you had installed. So get off your high horse.

I said I was using KCauldron, not cauldron.
My whole server is based on KCauldron, why would I try the mod with it? I couldn't even open my world.
It makes no sense.

Anyway, thanks for trying to help.
Here's my full log

KCauldron is Cauldron.

Yes and no...is Chisel 2 the same as Chisel 1?
Some people might say yes and other would say no. I bet you would say no.

Stop playing semantics. Any variant of bukkit+forge is UNSUPPORTED. Test without it and see if it still happens.

Same error running same mods in Forge 1.7.10 1517

Is there a trick to get in your error log the [NAME OF MOD] in front of every line?
That's kinda cool.

Do you have any chisel blocks manually added to FMP? That is automatic now.

I doubt it but possible. Which config would that be? I don't see a config for it.

microblocks.cfg

I remember editing this cfg on the recommendation of someone but going back to it being blank because it added a bunch of unrelated errors.

This is what it is right now:

#Configuration file for adding microblock materials for aesthetic blocks added by mods
#Each line needs to be of the form :
# is the unlocalised name or registry key of the block/item enclosed in quotes. NEI can help you find these
# may be ommitted, in which case it defaults to 0, otherwise it can be a number, a comma separated list of numbers, or a dash separated range
#Ex. "dirt" "minecraft:planks":3 "iron_ore":1,2,3,5 "ThermalFoundation:Storage":0-15

Ok well someone/something is adding chisel blocks to FMP manually. It's not really a problem though, it's a harmless error.

k cool thanks

Same issue with KCauldron 1.7.10 1517.168 in case it helps
