Streamfwd after upgrade to 8.1.5 doesn't parse netflow fields (bytes_in, bytes_out, packets_in, packets_out)

[Kim]

Hello, colleagues.

I'm using an independent stream forwarder installed on Ubuntu 22.04.05 as a service.

After updating to 8.1.5 bytes_in, bytes_out, packets_in, packets_out are always equal to zero.

If I stop the service and change /opt/streamfwd/bin/streamfwd from 8.1.5 to 8.1.3 and start sert service again, everything is ok. 

Anybody run into this?

thanks.

I am having the exact same problem. Did you manage to find a solution to this? 

Also how did you downgrade to the old ISF streamfwd version?
