Hi, regarding this bug... When carp information is about to be printed, it stops. All network activity has stopped by then. For example: > bridge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1280 > ether 02:48:9e:59:98:00 > inet 156.0.0.2 netmask 0xffffffc0 broadcast 156.0.0.63 > inet 156.0.0.10 netmask 0xffffffc0 broadcast 156.0.0.63 vhid 10 > nd6 options=9<PERFORMNUD,IFDISABLED> > load: 1.18 cmd: ifconfig 1683 [running] 4.14r 0.00u 0.01s 35% 2268k > load: 1.18 cmd: ifconfig 1683 [running] 4.59r 0.00u 0.01s 36% 2268k > load: 1.18 cmd: ifconfig 1683 [running] 4.85r 0.00u 0.01s 39% 2268k > load: 1.18 cmd: ifconfig 1683 [running] 5.05r 0.00u 0.01s 41% 2268k > load: 1.18 cmd: ifconfig 1683 [running] 5.27r 0.00u 0.01s 39% 2268k > load: 1.18 cmd: ifconfig 1683 [running] 5.48r 0.00u 0.01s 41% 2268k > load: 1.18 cmd: ifconfig 1683 [running] 5.69r 0.00u 0.01s 43% 2268k > ^C^C^C^Z > > > > > > load: 1.86 cmd: ifconfig 1683 [*carp_if] 31.26r 0.00u 30.67s 88% 2268k > load: 1.86 cmd: ifconfig 1683 [*carp_if] 31.42r 0.00u 30.67s 88% 2268k > ^Z^Z^Z^C^C^C^C > > load: 0.22 cmd: ifconfig 1683 [*carp_if] 645.27r 0.00u 30.67s 0% 2268k > load: 0.21 cmd: ifconfig 1683 [*carp_if] 645.81r 0.00u 30.67s 0% 2268k > load: 0.21 cmd: ifconfig 1683 [*carp_if] 646.17r 0.00u 30.67s 0% 2268k Eventually the kernel will panic: > panic: deadlkres: possible deadlock detected for 0xfffff800045b44a0, blocked for 900246 ticks Is this the same bug, Jason? I could try the patch on my bhyve cluster. Thanks, Nikos
