Thread-topic: [nv-l] High CPU Usage in ovwdb
Yes I got that one.

The problem is the new release of Tavve is doing something rather intensive 
with interface descriptions. (I think they are substituting in the local 
ifAlias on top of the normal ifDesc). Anyway, they have a fix NSN220011 that 
will revert the way Tavve works back to the way the previous version worked.
