Phantom forces spinning vessel, "SolveClosestApproach"

[Tokamak]

Sometimes, for no apparent reason, one of my vessels will start spinning a vessel around, sometimes very fast. Sometimes it's a small amount that my SAS can counteract, and sometimes it tumbles at literally multiple revolutions per second. Is this just something that happens to me? Is it a known kraken that I can do something about?

The couple of other bits of information that I have are that it most often (but not always) happens when I switch SOIs, and usually when it happens my console/log gets spammed with " [Orbit] SolveClosestApproach: solve took too many iterations, result incorrect"

Any thoughts?
