According to the literature, the usual culprit is, indeed, the stop
bath.  I wonder whether there is an ingredient unique to IR film that
causes the problem.  I had a similar problem with IR color film back
when E4 was the standard.  My local store had been sending it to their
regular processor, but when some otherwise excellent stuff came back
with pinholes--and, on one regular Ektachrome 400 roll, some frames
were solarized--I had the shop switch my stuff to Kodak processing and
the problems disappeared.
