A TV transmitter engineer told me about a length of RG213 that was being
used as a UHF attenuator, so it was intentionally running quite hot in
continuous broadcast service. Even then, it took 7 whole years for the
inner to migrate to touch the outer.

In normal amateur HF use, it will simply never happen within the
lifetime of the coax and/or the operator.
