Processing problem-my film has measles!

I have seen a posting or two, in the past, making reference to black spots
> on HIE-135. However, I cannot recall any definitive reason why they
> appear. My last batch of film has blemishes on the emulsion that look like
> air bells. These blemishes are random in distribution. All, on the
> negative, look white and some have a slightly thickened density on their
> perimeter (almost crater like in appearance but always rounded in form)
>
> My processing involves a pre-wash for some two minutes and then a standard
> Kodak-based approach. The film when removed from its wash seems to have
> extraordinary surface tension..the wash water really sits up on the
surface
> and even a good soak in foto-flo does little to arrest this behaviour. I
> wonder if the developer is also sitting up on the film surface too !
>
> My agitation is a blend of rotation and inversion and is aggressive enough
> ( I think) to eliminate any possiblity of air bells....mindful of the
> pre-wash.
>
> Any suggestions as to why I have some really lovely negatives with spots
> that remind me of measles !
>
> I would appreciate any advice
