[f-nsp] Errors from MLX card

[Jethro R Binks]

Hi all,

My usual friendly Brocade engineer is unavailable just now, so can I run 
this one past you for a view.

Brand new MLX chassis and line cards, just started putting this network 
together.  We are seeing OSPF instability between one box and its two peers
-- the three form a triangle, and two peers are both connected from the
same card just now.  In the logs of the box, we get this message 
regularly appearing:

Feb  8 21:14:37:A:System: Health Monitoring: TM Egress data errors detected on LP 1/TM 0

Taking a leap of faith, I rconsole to LP slot 1, and using "sh tm stats 
all-counters 0":

Ingress Counters:
...

   EGQ EnQue Byte Count:                     3951348364608
   EGQ Discard Pkt Count:                    0                    
   EGQ Discard Byte Count:                   0

and I guess those errors on the Egress Counters are not good.

What might this indicate?  Hardware fault on the slot or module?  Hardware
info appended for the interested, thanks for any comments.
