https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256217 --- Comment #3 from Christos Chatzaras <chris@cretaforce.gr> --- These are dedicated servers with no virtualisation. ---- NIC: em0: <Intel(R) PRO/1000 Network Connection> mem 0xf7000000-0xf701ffff irq 16 at device 31.6 on pci0 ---- 1) tcp_rack_load="YES" && "net.inet.tcp.functions_default=freebsd" && reboot = problem does NOT exist 2) tcp_rack_load="NO" && "net.inet.tcp.functions_default=freebsd" && reboot = problem does NOT exist ---- 3) tcp_rack_load="YES" && "net.inet.tcp.functions_default=rack" && reboot = the problem EXIST. Then if without reboot I "net.inet.tcp.functions_default=freebsd" the problem still EXIST. But when after I change to "freebsd" I run "kldunload -f tcp_rack" the problem does NOT exist. -- You are receiving this mail because: You are the assignee for the bug.
