I've said this before, but I've gotten that on fresh film taken into very humid conditions but not shot until a later outing. Perhaps a symptom of condensation or other negative effects of those conditions. Only certain films, most notably SFX200 and PanF+, when shot in south GA or FL. Haven't had any issues in years, but I don't shoot PanF+ anymore and I live in a less humid place now (well, normally!).
Thank you for your input. My films were replaced according to the batch number which Ilford admited was bad. Your suggestion does make sense anyway. And it applies to the above post by paulbarden too. I am going to change the purchase/storage/usage habits AND/OR intervals to minimize the risk of this happening in the future. Ilford is still my rollfilm choice number one for being reasonably priced and classic looking emulsions(FP4+ and HP5+). I still trust their QC, much more than Foma, which sadly is from my country.
