be aware that (the cheaper) solid conductor cable is not meant to be reinserted. 
You punch it down and never move it. Reinserting (ie bending) solid conductor 
cable will eventually result in cracks in the conductor which will give erratic 
and hard to diagnose conditions.

Any cable that's reinserted has to be (the more expensive) multi stranded cable.

The OP mentioned that the problem occured after a cable was disconnected and 
reconnected. I would first suspect that solid core ethernet cable was involved.

You can check which the cable is: multistranded is floppy and cannot support its 
own weight; solid core can partially support its weight - a foot or so of it 
will not bend.
