--- Comment #4 from Michael Tuexen <tue...@freebsd.org> --- This is strange. When using nc, did you enter CTRL-D on the client side right after starting the client? This would be like in the failing trace. The client initiates a connection is terminates it without transferring any data. I'm not aware of any jail specific stuff, which has to be dealt with in the TCP code. I don't think we ever tested RACK in jails, I never test TCP stuff in jails in general. So I'm surprised that there are jail specific issues, but maybe I'm missing some fundamental stuff here. -- You are receiving this mail because: You are the assignee for the bug.
