@doug-ami - I would recommend upgrading your firmware to the latest maintenance release (R10.9.4 at the time of this post). If you are still experiencing issues, please reply to this post with the output to "debug ip bgp" and "show ip bgp neighbor".

Please do not hesitate to let us know if you have any questions.

Thanks,
