Scrub is very likely to resolve it.  Note that scrub will drop (and log) invalid items,  so pay attention to what it logs and plan on doing a repair afterwards to pull in a copy from a different node,  assuming RF>1

I am getting these exceptions on one of the nodes, quite often, during compactions:

"java.lang.AssertionError: originally calculated column size of 84562492 but now it is 84562600"

Usually  this is on the same column family.

I believe this is preventing compactions from completing, and subsequently causing other performance issues for me.

Is there a way to fix that ? Would nodetool scrub take care of this ?
