UDP Server to Flow Decoder is 90% full. This is normal when the collector is starting. If it persists for hours, it may indicate that you are at your license threshold or your system is under-resourced

Hello

    I just installed a new elastiflow+kibana enviroment but I'm experiencing an issue on performance.

- The environmnet is hosted by enough resources

- I activated a basic trial license for 30 days
- I am reciving 30-100 flows per second (but I expect to get more than 1000) 
- I have the titled error while i run a "docker logs -f flow-collector"


Any idea on what is keeping the flow decoder full all the time (without impact the CPU)?

Thanks
Nico

I would refer you to this KB article for more information, but my initial guess would be having sufficient CPU allocated?
