Abaqus:warning message,Tangent directions used to enforced contact constraints for contact pair

Well I tried to search for a related thread and could not find one, so creating a new
one. But if such a thread exists, please direct me there, thank you. I
am trying to define the contact between two gears and it worked
perfectly before without Substrcture. But I receive a warning when I use
usbstructures. I do not want go into much details because I do not want
to confuse anyone. I wish to have answer only for following question:
I receive a warning as "Tangent directions used to enforced contact
constraints for contact pair (tooth-2-005,tooth-1-001) will not rotate
with either surface." I wish to know the exact meaning of the warning
and what are the possibilities to resolve it. Actually the calculation
in abaqus goes ahead inspite of the warning message and it worked till
few steps and then it gives me an error "too many increments required
for this step". I think may be it is better to resolve this warning
first and then work ahead on other other things.

*SURFACE INTERACTION, NAME=INTPROP-1
1.,
**
*SURFACE BEHAVIOR, PRESSURE-OVERCLOSURE=HARD
**
*CONTACT PAIR, INTERACTION=INTPROP-1, TYPE=SURFACE TO SURFACE
Rad_1.TOOTH-1-001, Rad_2.TOOTH-2-001

I think it is possible that more information is required on the topic and I will be happy to provide so in case required. Thank you.
