Need guidance on syslog from fabmgr

Hi all, I'm getting the following syslog (also not in standard format) on a 9010 running 4.3.1 + SMUs:

 RP/0/RSP0/CPU0:Nov 27 05:55:46.484 : fabmgr[222]: Fabric backplane crossbar 
link underwent link retraining to recover from a transient error: Physical  
slot 8

RP/0/RSP0/CPU0:Dec  4 16:26:14.186 : fabmgr[222]: Fabric backplane crossbar

RP/0/RSP0/CPU0:Dec  5 05:02:46.940 : fabmgr[222]: Fabric backplane crossbar

slot 8
RP/0/RSP0/CPU0:Dec  5 05:21:34.319 : fabmgr[222]: Fabric backplane crossbar 
link underwent link retraining to recover from a transient error: Physical  
slot 8

Any idea where to start looking to try to troubleshoot this?  I found out via show platform summary that physical slot 8 refers to slot 6, but beyond that I'm stumped.

Hi Aaron,

Collect the following and open an SR (if you open tomorrow in US hours I'll handle the case).

'show controllers fabric ltrace crossbar location 0/RSP0/CPU0'

'show log'

'show install active summary'

Thanks,

Sam

Ok, I opened a case about an hour ago under my CCO profile.  Let me know if you can't find it.
