Does anyone know what this message means in my system logs? It's showing up once per second. I have an MX204 running Junos 17.4R2.4

Hi !

 

There is a KB article for a similar type of messages on the TX side. 

https://kb.juniper.net/InfoCenter/index?page=content&id=KB32291&actp=METADATA

 

This seems to be a hardware issue. Please reboot the device once and see if the error stops. If it doesnt stop then it probably have to repaced via RMA. 

 

Please open a JTAC for further investigation if reboot doesnt fix it and get it replaced via RMA.

 

Hope this helps !!

While receiving a frame, the local buffer in the PFE - EA chip transmitted insufficient data because data could not be consumed by the u-kernel DRAM fast enough to keep pace with its input rate. Normally, such a problem is temporary, depending on transient peak loads within the system.

This unit is itself an RMA replacement for an earlier MX204 that had some other sort of low-level RAM or ASIC error. sigh.
