passport 8600 losing its routing capability intermittently

[mchauhan333]

This box is running 4.1.4 version and say every two weeks the switch loses its routing feature and you cannot ping anywhere outside each subnet.
the log message says
"2012-09-21 19:59:23 Local1.Info 159.207.200.2 CPU5
[09/21/12 11:58:55] HW INFO rarCheckConsistency: Record size 140 in hash bin 0x00077331 Next threshold 150"


any help!

Error Message "HW INFO rarCheckConsistency: Record size 140 in hash bin 0x00008ad7 Next threshold 150".

It can be explained as follows:- On the Passport, incoming packets are handled as internal data using :
1) hash pointer (queued in hash bin as FIFO; pointing to forwarding record)
2) forwarding record (internal data itself; originally incoming packets)

The logs above mean that the number of hash pointers queued in hash bin has exceeded the threshold (Record size), which could mean that the number of forwarding records awaiting for being forwarded is getting increased by some reason. This is just an indication of data pointer queue. This itself there would no problem and should be ignored except debugging purpose. The Hash table is used to increase the speed of searching the forwarding table of the RaptARU.

CR v4.1.3
In the CR its mentioned " Too many interfaces running routing protocols will cause serious problems like hash-bin inflation, lookup failures and serious scalability issues".

SOLUTION is to use the control-record-optimisation feature. Actually its a flag which should be enabled and then REBOOT for the flag to take effect.

Commands :
config bootconfig flags control-record-optimization true
save boot
