IOSXE-3-PLATFORM: STANDBY:2 process kernel: ERROR CVMX_L2C_ERR_TDT

I have this log message on a WS-C3850-48P running 03.03.04SE

%IOSXE-3-PLATFORM: STANDBY:2 process kernel: ERROR L2C_TADX_INT(0)[L2DSBE]: Data Single-Bit Error
 %IOSXE-3-PLATFORM: STANDBY:2 process kernel: ERROR CVMX_L2C_ERR_TDT: 0x4230000000185002

Any ideas ?

 

Thanks

Consulelo,The logs are

Consulelo,

The logs are informative. They says that the kernel has experienced a problem and the logs
are about where in the memory has this error occurred. Since it has happened only once, it
seems minor. If you see these errors popping constantly, that would be considered as a
hardware failure and in that case proceed with hardware replacement.

If we reload this switches as standalone (not in stack) - we don't see errors in logs.

 

Can you advise solution ?

Thanks

Hi dear 

Hi dear 

you need some structure in stack , before any solution becarfule about switches, shutdown all switches from power.

step 1 : first 2 switch make stack together. ( with same IOS , ...)

step 2 : if any thinks is normal added next switch , until the big problem happen again .

step 3: remove last switch and try for reboot all switch , if condition is normal , plz make text from last switches have a problem by ( show run ) and upload here

Re: IOSXE-3-PLATFORM: STANDBY:2 process kernel: ERROR CVMX_L2C_ERR_TDT

I also have received this error but we are running IOS Version 03.06.04.E on a WS-C3850-48P (Not stacked). I have only seen the error 1 time. I will be monitoring it also. Are there any bugs logged on this error yet?
