Looks like its hitting a bug

Looks like its hitting a bug , have you already upgraded the software image ? , you have tracebacks errors which could be software or hardware , if you have already upgraded through software you may have a defect itself in hardware and need to replace it

1 upgrade the software try and fix it that way

2 Run it by TAC  if software is not fixing it , may need replacement
