OK, after some more testing, I determined that FAR is causing the spinning. I removed FAR and the rocket stopped spinning. The design of my rocket is simple. It's a 2-stage rocket done with KW Rocketry parts, a 4-unit tank in the first stage and a 2-unit tank in the second stage. The command cube sits at the top in a fairing base and two cone fairing halves are covering it. There was also a RemoteTech antenna (offset into the tank) and MechJeb2 remote (offset into the tank). But I verified and these two are not the problem. I can't give you the craft file as I would have to attach my modified parts as well (I'm not using stock/mod parts, I've created my own parts based on KW). Another thing I tried is launching without the fairings (only the cube on the base) and that seemed to not spin my rocket. So I'm thinking the problem is with FAR and fairings. With FAR and without fairings, there is no problem; and without FAR and with fairings, there is no problem. I'm looking into this right now. EDIT: After some preliminary tests, it seems that FAR relies on the part title to determine if it is a fairing or not, and my part title was not using their convention. After adding my part title to it, the spinning seemed to have stopped. I will continue to test this and if the problem persists I'll post my findings. I don't want to hijack the OPs issue -- the problem could be caused by something else in their case. However, OP, if through trial an error by eliminating parts, you determine which part is giving you aero issues, take a look in FAR's Part Classification tab. That might fix your issue.

I'm having the same issue with rolling. I tried a number of things, from unplugging the joystick to changing part configuration to avoid any kind of clipping that could cause it. I still found no solution. As the OP mentioned, reverting back to the original game settings works for a while, then out of nowhere it starts the spinning again. There is either a bug in KSP or one of the mods. I'm definitely curious about the solution to this because this has been driving me nuts for the past 4-5 days now.
