I've got an older install of netflow analyzer (9.8 build 9800) that has been trucking along just fine until recently.

For some reason it is reporting 1000s new interfaces for routers that dont have 1000s of interfaces.

The highest is 56179 new interfaces for one router.

The only routers that were impacted were Mikrotik, the cisco ones are fine.

When I go into license management the console is very slow to respond.  

If I select the device (which selects all the interfaces below) and hit delete after a while i'll get an error "interfaces not deleted"

Im guess all these interfaces are causing lots of database lookups = slow performance.

For this install it won't matter if all data is lost as we use something else for billing, this is more for visibility \ troubleshooting so I tried the droptables and rawcleanup scripts in the troubleshooting folder.

The problem doesn't seem to be getting worse (as in the number of new interfaces seems to be static - just trying to cleanup)

Anyone got any suggestions other than do a fresh install?

Thanks

Bryan
