"show tm log" shows "detected TM egress error" and repeated constant "TM Reg offset" for that linecard.

After the linecard is moved to a different chassis, "show tm log" continues to show "TM Reg offset" for that same linecard. Physical troubleshooting shows that "TM Reg offset" messages follow the linecard regardless of where it's installed.

Environment
  • NetIron MLXe
  • BR-MLX-10GX4-X
  • NI 5.3.00b
Cause
