Please see: src/vnet/session-apps/echo_client.c src/vnet/session-apps/echo_server.c
In there you would see that fifo-size is shifted left by 10 (that means 4 becomes 4096). Maybe you want to try with 8 or 16? Hopefully, Florin can shed some light about the usage of 4096 for the fifo- size... which would eventually mean a fifo of 4M entries? > That’s why I want to use CLI commands to test SCTP.

I am not sure why you see nclients=2 in test_sctp.py... there's no mention of it on latest MASTER... > > You mean you use the same commands in my last mail, and there is no issue?
