Possible fabric hw fault detected

‎03-11-2016 05:13 AM

Hi!

 

I have MX240 with 2 RE-S-1800x4 running on 15.1R2.9 (because i want to use vxlan).

Also installed 2 MPC 3D 16x 10GE linecards.

1 full-view BGP session and 1GB transit traffic load.

 

In the messages log i see strange records^

Mar 11 11:16:41 cr3 fpc2 PFE 0: Possible fabric hw fault detected, total 88 times since up.
Mar 11 11:16:41 cr3 fpc2 PFE 0: exceeding aggr threshold 100, curr/last stats: pkt_crc 0/0, pkt_err 26825/26725, ptuse 0/0
