Obviamente, não tenho como dizer o que poderia ter causado este erro sem ler o fonte (e não tenho tempo agora). Mas suspeitas imediatas: * erro de memória * overcommit de memória * tentando alocar endereço/tamanhos inválidos de memória Se nada, *absolutamente nada* foi mudado no servidor, eu olharia os dois primeiros casos. Se algo foi mudado, eu olharia o que foi mudado. > Dec 12 09:34:56 PROXY kernel: [147289.394495] RSP: 0018:ffff88013255bcf8 > EFLAGS: 00010002 > Dec 12 09:34:56 PROXY kernel: [147289.394498] RAX: 0000000000000000 RBX: > 00000000003a0270 RCX: 0000000000000008 > Dec 12 09:34:56 PROXY kernel: [147289.394502] RDX: ffff880007052090 RSI: > 00000000000080d0 RDI: ffffffff8110661a > Dec 12 09:34:56 PROXY kernel: [147289.394505] RBP: 0000000000000246 R08: > 0000000000000240 R09: ffff880132497600 > Dec 12 09:34:56 PROXY kernel: [147289.394508] R10: 0000000000000241 R11: > ffffffff811540fd R12: ffffffff81479f10 > Dec 12 09:34:56 PROXY kernel: [147289.394511] R13: 00000000000080d0 R14: > 00000000000080d0 R15: 0000000000000008 > Dec 12 09:34:56 PROXY kernel: [147289.394516] FS: 00007f7183799700(0000) > GS:ffff880007040000(0000) knlGS:0000000000000000 > Dec 12 09:34:56 PROXY kernel: [147289.394519] CS: 0010 DS: 0000 ES: 0000 > CR0: 0000000080050033 > Dec 12 09:34:56 PROXY kernel: [147289.394522] CR2: 00000000003a0270 CR3: > 00000001ab28b000 CR4: 00000000000006e0 > Dec 12 09:34:56 PROXY kernel: [147289.394526] DR0: 0000000000000000 DR1: > 0000000000000000 DR2: 0000000000000000 > Dec 12 09:34:56 PROXY kernel: [147289.394530] DR3: 0000000000000000 DR6: > 00000000ffff0ff0 DR7: 0000000000000400 > Dec 12 09:34:56 PROXY kernel: [147289.394534] Process ifconfig (pid: 7888, > threadinfo ffff88013255a000, task ffff88013fda0e20) > Dec 12 09:34:56 PROXY kernel: [147289.394539] ffff88013255bd68 > ffffffff8110661a 00000008dc6af600 ffffffff816d1570 > Dec 12 09:34:56 PROXY kernel: [147289.394545] <0> ffffffff81342b00 > ffff880132497600 ffff8801df25c378 ffffffff811394a4 > Dec 12 09:34:56 PROXY kernel: [147289.394551] <0> ffff8801abe07cf0 > ffffffff8110661a ffffffff816d1570 ffff8801df25c300 > Dec 12 09:34:56 PROXY kernel: [147289.394567] [<ffffffff8110661a>] ? > __seq_open_private+0x17/0x4e > Dec 12 09:34:56 PROXY kernel: [147289.394574] [<ffffffff811394a4>] ? > seq_release_net+0x0/0x3b > Dec 12 09:34:56 PROXY kernel: [147289.394579] [<ffffffff8110661a>] ? > __seq_open_private+0x17/0x4e > Dec 12 09:34:56 PROXY kernel: [147289.394583] [<ffffffff8113959e>] ? > seq_open_net+0x4f/0x85 > Dec 12 09:34:56 PROXY kernel: [147289.394590] [<ffffffff811318d4>] ? > proc_reg_open+0xc7/0x14d > Dec 12 09:34:56 PROXY kernel: [147289.394595] [<ffffffff8113180d>] ? > proc_reg_open+0x0/0x14d > Dec 12 09:34:56 PROXY kernel: [147289.394600] [<ffffffff810edc7e>] ? > __dentry_open+0x19d/0x2bf > Dec 12 09:34:56 PROXY kernel: [147289.394606] [<ffffffff810f95df>] ? > do_filp_open+0x4e4/0x94b > Dec 12 09:34:56 PROXY kernel: [147289.394612] [<ffffffff8110262d>] ? > alloc_fd+0x67/0x10c > Dec 12 09:34:56 PROXY kernel: [147289.394616] [<ffffffff810eda0f>] ? > do_sys_open+0x55/0xfc > Dec 12 09:34:56 PROXY kernel: [147289.394623] [<ffffffff81010b42>] ? > system_call_fastpath+0x16/0x1b > Dec 12 09:34:56 PROXY kernel: [147289.394681] RSP <ffff88013255bcf8> > Dec 12 09:34:56 PROXY kernel: [147289.394688] ---[ end trace > 4e3212ab62200357 ]--- > > Mas não sabemos qual a versão do kernel, etc, etc... ..C.. -- Mais sobre o Ubuntu em português: http://www.ubuntu-br.org/comece Lista de discussão Ubuntu Brasil Histórico, descadastramento e outras opções: https://lists.ubuntu.com/mailman/listinfo/ubuntu-br
