Done Can't login anymore

Hi, I just cant login to the server anymore. Get always kicked with following message: Connection lost - Internal Server error.
So i cant create a ticket.
I think it has to do with a fluid extraction pipe (not the buildcraft one, I just cant remember the mods name). Last thing I did was removing it from a modular machinery because it seems they don't work correct. After I broke this extraction pipe and picked it up i got kicked.

 

Its still the problem.
log:

maybe someone from staff can look into it?

 

Topic is solved for now.
TheeForgotten removed all Fluid pipes from Cyclic Mod in my base.
I can login without kicks now.

Hint for other players: Don't use "Fluid pipes" from Cyclic mod in your base!
