Background:
I've created a 1.7.10 custom mod pack I've been having major lag problems with suspected memory leaks. The game will run for 15-30 mins before maxing out the amount of memory given to it (anywhere from 3-6 gb). The issue is not related to chunk generation as I've tested it on an island world in the middle of the ocean without moving and the issue still occurs. The issue is probably with one of the mods or a mod conflict or the JVM argument, so let me know if anything is a known offender. Thanks

P.S.

If anyone could identify unnecessary mods, that would also be helpful.

Also, if someone could identify why Thermal Dynamics (which crashes both client and server without crast reports,) is not working with these mods, that would be very great. Thanks!

Setup:
Intel Core i7 6700HQ
8GB RAM

GTX960M 4GB VRAM
Windows 10 64 Bit system
JRE 8u20 x64
Forge 10.13.4.1614
