..what causes this is the use of a non-acid or low-acid fix.
if you are having this condition you need to use a stop bath, a strong one!
i would also add some sodium sulfite to the stop just to make sure your developer action is truly stopped.
use a good fix. the Kodak rapid fix is best.
leave the lights off till the film is completely fixed.

Any use of other individual chemicals, will show different results.
