Title Possible memory leak

Launcher Type Twitch Desktop App

Modpack Custom

Modpack version 1.12.2

Have you modified the pack? Yes

Link to log file http://paste.feed-the-beast.com/view/c58354e0

Details of the issue After 5-10 minutes of playing my custom-made 1.12.2 pack, my game starts to get insane lag spikes every 15 seconds or so. It seems that Java GC is mostly full (94% of allocated memory used), then lag spike, then it drops to 80-ish% of allocated memory used.

This only started happening, from what I can tell, once Factory Tech updated to 1.0.2. I don't have time to verify this mod is the problem right now, but will check soon.

Latest log: http://paste.feed-the-beast.com/view/ba50ae1d

Allocated memory: 4608 MB
Additional java parameters: None
Total memory on the machine: 16 GB

EDIT: It does seem that Factory Tech is the issue. This stopped when I tore down the setup I had using its machines, so the problem may be tied to rendering. The F3 graph said it's gameRenderer and display_update taking most of the memory when the spikes happened.

EDIT2: This was my F3 screen right after a spike.
