Have tried search this archive and googled for a solution but nothing came up. The interface is a elink and i have no issues on other interface Fa0/1 in the same router. Any hint on how i can go about troubleshooting this?

I've never seen this error before. If I'm parsing the error message correctly, it appears as an RPN stack underflow occurs when Cricket tries to scale the values from the RRD file (i.e. turning octets/second into bits/second).

Ufortunately, I don't know enough about cricket to give a meaningful answer on how to fix this. You should probably ask your question on the cricket-users [1] mailing list instead, but it would be nice if you cross-posted it here, since the problem might be related to the default cricket-config that ships with NAV.
