Do this:
make an ACL that matches on the Loopback0 address and the ip address for the server.
ie:
access-list 101 permit ip host <loopback0> host <server>
Then do:
debug ip packet 101
and see if you see the router sending out packets towards the server /*or put a sniffer on the wire and see*/
I'm not sure when we update this counter:
9 export packets were dropped due to adjacency issues
Make sure "sh cef drop" doesn't show counters going up.

yes...i see them... and
Flow export v5 is enabled for main cache Exporting flows to x.x.x.x (2057) Exporting using source interface Loopback0 Version 5 flow records 505367177 flows exported in 160011153 udp datagrams 0 flows failed due to lack of export packet 1 export packets were sent up to process level 0 export packets were dropped due to no fib 9 export packets were dropped due to adjacency issues 0 export packets were dropped due to fragmentation failures 0 export packets were dropped due to encapsulation fixup failures
But no data is sent from the router.

Hi all :)
I have a Cisco 7204 VXR (NPE 200) with a 12.2(19a) IOS version running BGP.
I know it?s a deferral ios version. But before changing it I would like to know why netflow doesn?t work I export flows to a linux machine with a daemon talking in a x udp port. But The machine receive nothing!. The machine receive flows of other routers in the same network, so is not OS/FW related. The connectivity is OK and cef is running in the router. The only thing i think to do is to upgrade the IOS but... someone has any idea of what?s wrong with the 7204?, it doesn?t send flows to the server. It seems very strange for me.There?s no netflow bugs in that ios that could affect it. :?
thanks for your ideas :)
cheers
Javier
