It seems to be an issue with the redstone ether. The error log mentions dimension 1 and -23. In the Tekkit_Lite_Server_0.6.1\world directory there are three folders named DIM1, DIM-1, and DIM-23, all with redstone ether folders in them. Would disabling the Wireless Redstone mod fix it?

I have the same issue too. It started after I updated to the new launcher. I also went to the nether for the first time in that world. The server tells me it has detected leaking worlds in memory.
