Decidi iniciar outra thread porque a antiga já está bem atrás. A thread original é essa: http://www.fug.com.br/historico/html/freebsd/2008-09/msg00069.html Pois bem, só pra relembrar: meu servidor vive dando kernel panic onde o "current process" sempre é o dummynet. Hoje pela manha teve outro panic e pude fazer o backtrace. Se alguém puder ajudar ou dar uma luz, ficaria grato. O erro sempre é em _mtx_lock_sleep() (kern_mutex.c). Não verifiquei nas outras vezes, mas dessa vez, o erro foi na linha 341: if (TD_IS_RUNNING(owner)) { Estou pensando em verificar a macro TD_IS_RUNNING e tentar adicionar uma chacagem antes, pois acho que "owner" está indo com um valor inválido (suspeito de ser NULL). Só que to meio receioso de acabar arrombando o kernel. :P Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x258 fault code = supervisor read data, page not present instruction pointer = 0x8:0xffffffff8047c70e stack pointer = 0x10:0xffffffffae4c6ab0 frame pointer = 0x10:0xffffffffae4c6ad0 code segment = base 0x0, limit 0xfffff, type 0x1b ~ = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 47 (dummynet) panic: from debugger cpuid = 0 Uptime: 3d16h56m46s Physical memory: 4002 MB Dumping 508 MB: 493 477 461 445 429 413 397 381 365 349 333 317 301 285 269 253 237 221 205 189 173 157 141 125 109 93 77 61 45 29 13 #0 0xffffffff80487aca in isbufbusy () at /usr/src/sys/kern/kern_shutdown.c:254 254 } (kgdb) bt #0 0xffffffff80487aca in isbufbusy () at /usr/src/sys/kern/kern_shutdown.c:254 #1 0xffffffff80487aef in doadump () at pcpu.h:194 #2 0xffffffff80487fe8 in boot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:408 #3 0xffffffff80488447 in panic (fmt=Variable "fmt" is not available. ) at /usr/src/sys/kern/kern_shutdown.c:559 #4 0xffffffff801bd817 in db_panic (addr=Variable "addr" is not available. ) at /usr/src/sys/ddb/db_command.c:433 #5 0xffffffff801bde6c in db_command_loop () at /usr/src/sys/ddb/db_command.c:401 #6 0xffffffff801bfb7f in db_trap (type=Variable "type" is not available. ) at /usr/src/sys/ddb/db_main.c:222 #7 0xffffffff804b06d5 in kdb_trap (type=12, code=0, tf=0xffffffffae4c6a00) at /usr/src/sys/kern/subr_kdb.c:499 #8 0xffffffff8075dabd in trap_fatal (frame=Variable "frame" is not available. ) at /usr/src/sys/amd64/amd64/trap.c:724 #9 0xffffffff8075de94 in trap_pfault (frame=0xffffffffae4c6a00, usermode=0) at /usr/src/sys/amd64/amd64/trap.c:613 #10 0xffffffff8075e84a in trap (frame=0xffffffffae4c6a00) at /usr/src/sys/amd64/amd64/trap.c:464 #11 0xffffffff80743b4e in alltraps_pushregs_no_rdi () at /usr/src/sys/amd64/amd64/exception.S:159 #12 0xffffff00bbe56c50 in ??
