Ciao a tutti, volevo sottoporvi questo problema.
Ho un server con debian 4.0 e kernel 2.6.18-5-xen-686, 4 gb di ram che ad intervalli costanti si blocca completamente e deve essere riavviato. Una volta riavviato tutto รจ ok. Il file /var/log/messages prima del blocco riporta questo errore Apr 23 02:13:44 nodo1 kernel: oom-killer: gfp_mask=0xd0, order=0 Apr 23 02:13:44 nodo1 kernel: [<c013f20f>] out_of_memory+0x25/0x13a Apr 23 02:13:44 nodo1 kernel: [<c01406ed>] __alloc_pages+0x1f5/0x275 Apr 23 02:13:44 nodo1 kernel: [<e14cf508>] svc_recv+0xdc/0x3e4 [sunrpc] Apr 23 02:13:44 nodo1 kernel: [<c01157a9>] default_wake_function+0x0/0xc Apr 23 02:13:44 nodo1 kernel: [<e151d51a>] nfsd+0x100/0x30a [nfsd] Apr 23 02:13:44 nodo1 kernel: [<e151d41a>] nfsd+0x0/0x30a [nfsd] Apr 23 02:13:44 nodo1 kernel: [<c010293d>] kernel_thread_helper+0x5/0xb Apr 23 02:13:44 nodo1 kernel: Mem-info: Apr 23 02:13:44 nodo1 kernel: DMA per-cpu: Apr 23 02:13:44 nodo1 kernel: cpu 0 hot: high 186, batch 31 used:34 Apr 23 02:13:44 nodo1 kernel: cpu 0 cold: high 62, batch 15 used:58 Apr 23 02:13:44 nodo1 kernel: DMA32 per-cpu: empty Apr 23 02:13:44 nodo1 kernel: Normal per-cpu: empty Apr 23 02:13:44 nodo1 kernel: HighMem per-cpu: empty Apr 23 02:13:44 nodo1 kernel: Free pages: 2964kB (0kB HighMem) Apr 23 02:13:44 nodo1 kernel: Active:13457 inactive:14901 dirty:8 writeback:544 unstable:0 free:741 slab:61550 mapped:8 pagetables:118 Apr 23 02:13:44 nodo1 kernel: DMA free:2964kB min:2916kB low:3644kB high:4372kB active:53828kB inactive:59604kB present:532480kB pages_scanned:208360 all_unr$ Apr 23 02:13:44 nodo1 kernel: lowmem_reserve[]: 0 0 0 0 Apr 23 02:13:44 nodo1 kernel: DMA32 free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Apr 23 02:13:44 nodo1 kernel: lowmem_reserve[]: 0 0 0 0 Apr 23 02:13:44 nodo1 kernel: Normal free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Apr 23 02:13:44 nodo1 kernel: lowmem_reserve[]: 0 0 0 0 Apr 23 02:13:44 nodo1 kernel: HighMem free:0kB min:128kB low:128kB high:128kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Apr 23 02:13:44 nodo1 kernel: lowmem_reserve[]: 0 0 0 0 Apr 23 02:13:44 nodo1 kernel: DMA: 23*4kB 19*8kB 0*16kB 1*32kB 2*64kB 2*128kB 1*256kB 0*512kB 0*1024kB 1*2048kB 0*4096kB = 2964kB Apr 23 02:13:44 nodo1 kernel: DMA32: empty Apr 23 02:13:44 nodo1 kernel: Normal: empty Apr 23 02:13:44 nodo1 kernel: HighMem: empty Apr 23 02:13:44 nodo1 kernel: Swap cache: add 18884, delete 18884, find 11408/13744, race 0+0 Apr 23 02:13:44 nodo1 kernel: Free swap = 1928396kB Apr 23 02:13:44 nodo1 kernel: Total swap = 1951888kB Apr 23 02:13:44 nodo1 kernel: Free swap: 1928396kB Apr 23 02:13:44 nodo1 kernel: 133120 pages of RAM Apr 23 02:13:44 nodo1 kernel: 0 pages of HIGHMEM Apr 23 02:13:44 nodo1 kernel: 18829 reserved pages Apr 23 02:13:44 nodo1 kernel: 28414 pages shared Apr 23 02:13:44 nodo1 kernel: 0 pages swap cached Apr 23 02:13:44 nodo1 kernel: 8 pages dirty Apr 23 02:13:44 nodo1 kernel: 544 pages writeback Apr 23 02:13:44 nodo1 kernel: 8 pages mapped Apr 23 02:13:44 nodo1 kernel: 61550 pages slab Apr 23 02:13:44 nodo1 kernel: 118 pages pagetables Ho cercato su google e simili ma non ho trovato una soluzione e non ho nemmeno capito che problema sia. Voi potete aiutarmi? Grazie, ciao! Matteo -- Per REVOCARE l'iscrizione alla lista, inviare un email a debian-italian-requ...@lists.debian.org con oggetto "unsubscribe".
