you didn't pull them from the fridge and develop did you? 
 
only other thing would be solution temperatures being too high. did that to a roll of E-6. once. emulsion just sloughs off. 
 
check wash temp. simple kitchen thermometers are fine, just tape it to water stream. dial thermometers are ok, you don't need a real accurate check, just 60-75 for wash temp, you want to know if it gets to 80, 90, 120, 210 deg f....... 
 
B&W is generally pretty forgiving of temperatures in developing. 
 
the only other possible thing would be having it soak too long, but that's a real long shot. probably high temp somewhere.

Hello everyone, 
 
seems like I got a strange problem with Konica IR: This evening, I 
developed two Konica films (D-76 stock, Tetenal stop bath, Tetenal 
Superfix, a combination I often used succesfully before). During the 
final washing I had to realize that on both films the gelatine on the 
back side was virtually dissolving. Most of the negs were ruined this 
way. Fortunately, it was a series I can shoot again... The films are 
from the 1999 production (expiry date 3/2000). Of course, I kept them in 
the freezer/fridge... At first, I thought that something was wrong with 
my chemicals. I had however used the same solutions before with a roll 
of HIE, which was absolutely okay. After I encountered the problems with 
Konica IR, I used the chemicals in question once more for a roll of TMAX 
400 (maybe somewhat risky). Everything worked just fine...  But somehow, 
there MUST be a lesson to be learned... The only possible reason I can 
think about now was that maybe the water went too warm, while I was 
washing the Konica films ? Any suggestions will be greatly appreciated, 
 
Eckhard
