Yes, this has happened to me, although lately, I have been doing my sweating... getting rid of toxins, I am sure. All of the comments so far are right on about why this happens and that it is not that unusual. In fact, I think it means your body is letting the yoga do its job. Both my best yoga teacher and my therapist have said, "The issues are in the tissues." My therapist added that the tissues don't know time...so a memory or event feels contemporary to your body.
BTW, not surprising to happen during hip openers... most women store their stress in their hips.
