The above screenshot is just after the test started, Port 1 started with 3 million connections. It is very high compared to port0 connections (150K ).

@SSam009 can you please share the config file you used and also the cmd line to start Warp17?

Is there a DUT in between? Does it act as TCP proxy for the sessions?

What version of Warp17 are you running?

Thanks, Dumitru

SSam009 commented 6 years ago

@dceara I am using latest code (dev-common) . There is a DUT between the interfaces of the same host, I don't think it acts as TCP Proxy.

@SSam009 can you also please share your full config? Was this working with v1.8?

I've tried on my setup with your configuration and I didn't see this problem, can you please post the command line you use to launch warp17 as well?
