Hi, I've got about 30 machines which panic sometimes in different places but with the same panic message: "negative refcount 0xfffffe0007f1b4d4". They are running under 9.0-STABLE@r234600M. Trace looks like this: db:0:kdb.enter.panic> bt Tracing pid 0 tid 100037 td 0xfffffe00074918e0 kdb_enter() at kdb_enter+0x3b panic() at panic+0x180 ifa_free() at ifa_free+0x5d ip_input() at ip_input+0x559 netisr_dispatch_src() at netisr_dispatch_src+0x152 ether_demux() at ether_demux+0x18d ether_nh_input() at ether_nh_input+0x285 netisr_dispatch_src() at netisr_dispatch_src+0x152 em_rxeof() at em_rxeof+0x1a6 em_handle_que() at em_handle_que+0x4c taskqueue_run_locked() at taskqueue_run_locked+0x93 taskqueue_thread_loop() at taskqueue_thread_loop+0x3e fork_exit() at fork_exit+0x135 fork_trampoline() at fork_trampoline+0xe --- trap 0, rip = 0, rsp = 0xffffff8000323cb0, rbp = 0 --- or this: db:0:kdb.enter.panic> bt Tracing pid 3502 tid 100175 td 0xfffffe0007fb1470 kdb_enter() at kdb_enter+0x3b panic() at panic+0x180 ifa_free() at ifa_free+0x5d ip_output() at ip_output+0x6ab tcp_output() at tcp_output+0xe40 tcp_usr_connect() at tcp_usr_connect+0x109 soconnect() at soconnect+0x13f kern_connect() at kern_connect+0xde sys_connect() at sys_connect+0x41 amd64_syscall() at amd64_syscall+0x348 Xfast_syscall() at Xfast_syscall+0xf7 --- syscall (98, FreeBSD ELF64, sys_connect), rip = 0x5ecaa93c, rsp = 0x5f99ec78, rbp = 0x5f349c10 --- and I have more. Is this known issue? If it is not, I've got textdumps and can send to anyone who wants to help me. Thanks in advance. -- Andrey Zonov
