Hello,
I would really encourage you to open Service Request with Cisco TAC for this case. It is not only for a purpose of goot analysis and tracebacks decode. TAC is also documenting all the occurrencies which can be used later. Other thing is that TAC has a good interface with Development team if detailed analysis of the problem will be needed.
Please let me know if you have problems opening TAC SR.
Nik
