Description (partial)

After executing "show tech-support fabric" on Cisco ASR 9000 router running 6.6.3 software, continuous log messages as below start appearing in log buffer every 6 minutes.

RP/0/RSP1/CPU0:R11-PE3-A9006#show logging | i spio
Thu Dec  5 13:52:08.834 UTC
RP/0/RSP1/CPU0:Dec  5 13:41:28.586 UTC: spio_pd_show_protocol_ltrace[69582]: Invalid arguments
RP/0/RSP1/CPU0:Dec  5 13:47:28.928 UTC: spio_pd_show_protocol_ltrace[66173]: Invalid arguments
These logs are actually triggered by "show spio platform protocol all trace" command, but since "show tech fabric" includes this "show spio" command, the logs are seen when show tech fabric collection is done as well.

It seems ziplogger/paltx is being invoked when "show spio platform protocol all trace" command is executed, but maybe not properly, and that results in the log messages.

Execute "show spio platform protocol all trace" or "show tech-support fabric" on ASR 9000 routers running IOS-XR Release 6.6.3 software.
