1.1.8 Rednet Lag

[ninjaconor]

I've just updated my server to 1.1.8 and have been experiencing a lot of lag. Using Tickprofiler I've discovered the rednet cables in my nether base are generating about 100x more traffic than anything else. There are only 40 cable blocks though and all they are doing is keeping my redstone lamps on. If I delete the cables everything runs fine, but I'm sure they shouldn't be causing such lag in the first place. Has anyone encountered this and, if so, did you find a solution?

EDIT: Just tried removing each mod and restarting individually. Thermal Expansion seems to be clashing somehow. Will post more if I find a solution.

Maybe a stupid question? But what and how do u do, to do this tickprofiling for finding out what causes load on server?
