FTB Interactions pauses and crashes

#1

When I am playing FTB Interactions version 1.7.0, the game pauses every 1-2 hours for 10+ minutes at a time. Some of the time after a pause, the game crashes, it goes to a screen that says “Shutting down internal server…” and then it quits to the launcher (I’m using the legacy launcher). This seems to happen more often after some time spent playing. (I looked at the log and it may have something to do with an Ender IO DarkSteelUpgrade?).
