And command like 'ipfw pipe show' - emits no warnings. So warning are observed only in case if particular pipe or pipes list is shown. How to reproduce: ----------------- Install 9.3-RELEASE Load ipfw.ko and dummynet.ko Create some pipes ipfw pipe 1 config bw 5bit/s ipfw pipe 2 config bw 5bit/s Create pipe with mask ipfw pipe 3 config bw 5bit/s mask src-ip 0xffffffff Configure ipfw ipfw add 100 pipe 3 ip from any to me Disable pipe expiration sysctl net.inet.ip.dummynet.expire=0 Then generate some traffic. For my case it was enough to have 260+ entries in pipe. Now command like ipfw pipe show 3 or ipfw pipe show 1,3 will emit few kernel warnings in console and in /var/log/messages. And just 'ipfw pipe show' works ok. -- You are receiving this mail because: You are the assignee for the bug.
