[AusNOG] Cisco LNS - dataplane errors

[Joseph Goldman]

Hi All,

  Cisco 7204-G2, running as an LNS.

  Has anyone ever come across this error:

.Aug 10 01:58:39: VPDN uid:2171 Error setting up dataplane; set app req

  Basically the router accepts sessions up to what seems a certain 
subscriber count then once that number is online starts generating these 
errors.

  At best guess it is a full, finite resource. The number of allowed 
subscribers is slowly reducing, what I don't know is if this is due to 
bad garbage collection so to speak (i.e. 'stuck' sessions in the 
dataplane, that dont show in 'show users') or if the dataplane itself is 
actually dying/dead. If we kick a user offline or clear tunnels cleanly 
- users will re-connect back up to that number of subscribers (first in 
best dressed), which is what sparked this line of thinking.

  Anyone who has experienced similar or knows this a bit more in-depth, 
your help would be appreciated, as its got me scratching my head so far.

Thanks,
Joe
