Package: coreutils Version: 5.97-5.3 Severity: normal
Hi, first, I'd like to note that I report this problem against the coreutils package because I don't really know where else to report it (linux-image-something?). Secondly, the problem description: I recently had to create a big file, and ran this: # dd if=/dev/zero of=/srv/xen/disks/vm1.xm obs=1024K count=20000 seek=10000 conv=notrunc The effect, apart from growing the file to an unspecified size (it came out at 31G instead of 20), this brought my machine into an unsusable state, meaning the machine was unresponsive from the console for about half an hour at least, and it killed all X related stuff, thus messing up the display (I didn't find a way to correct this w/o a reboot). Over the network, the machine was accessible once the dd process was killed by the kernel. In the kernel log, I find messages like these (exerpt): Sep 16 14:26:56 debian kernel: DMA: 265*4kB 159*8kB 1*16kB 1*32kB 1*64kB 1*128kB 1*256kB 1*512kB 1*1024kB 1*2048kB 0*4096kB = 6412kB Sep 16 14:26:56 debian kernel: DMA32: empty Sep 16 14:26:56 debian kernel: Normal: empty Sep 16 14:26:56 debian kernel: HighMem: empty Sep 16 14:26:56 debian kernel: Swap cache: add 125033, delete 124855, find 11742/20953, race 0+13 Sep 16 14:26:56 debian kernel: Free swap = 3970792kB Sep 16 14:26:56 debian kernel: Total swap = 4194296kB Sep 16 14:26:56 debian kernel: Free swap: 3970792kB Sep 16 14:26:56 debian kernel: oom-killer: gfp_mask=0x201d2, order=0 Sep 16 14:26:56 debian kernel: Sep 16 14:26:56 debian kernel: Call Trace: Sep 16 14:26:56 debian kernel: [<ffffffff802a2a0c>] out_of_memory+0x2e/0x180 Sep 16 14:26:56 debian kernel: [<ffffffff8020fb51>] __alloc_pages+0x220/0x2a9 Sep 16 14:26:56 debian kernel: [<ffffffff8025e30e>] thread_return+0x5d/0xfc Sep 16 14:26:56 debian kernel: [<ffffffff80213012>] __do_page_cache_readahead+0xd4/0x24d Sep 16 14:26:56 debian kernel: [<ffffffff80228b79>] sync_page+0x0/0x42 Sep 16 14:26:56 debian kernel: [<ffffffff88190a46>] :dm_mod:dm_any_congested+0x38/0x3f Sep 16 14:26:56 debian kernel: [<ffffffff8819258a>] :dm_mod:dm_table_any_congested+0x46/0x63 Sep 16 14:26:56 debian kernel: [<ffffffff88190a46>] :dm_mod:dm_any_congested+0x38/0x3f Sep 16 14:26:56 debian kernel: [<ffffffff80213878>] filemap_nopage+0x148/0x314 Sep 16 14:26:56 debian kernel: [<ffffffff80208e14>] __handle_mm_fault+0x65f/0xe85 Sep 16 14:26:56 debian kernel: [<ffffffff8020ba24>] do_page_fault+0xd9b/0x112f Sep 16 14:26:56 debian kernel: [<ffffffff8025e30e>] thread_return+0x5d/0xfc Sep 16 14:26:56 debian kernel: [<ffffffff80390b65>] sock_ioctl+0x1c1/0x1e5 Sep 16 14:26:56 debian kernel: [<ffffffff802417ef>] do_ioctl+0x21/0x6b Sep 16 14:26:56 debian kernel: [<ffffffff8025c4d7>] error_exit+0x0/0x6e I had to reboot in order to get back to a sane working state, but found out, that I needed one more of these files. This time, instead of using 'dd', I used 'cp' to create a copy, and it worked like a charm, not even slowing my computer down too much. The computer in question is an AMD64 X2 machine with 2G RAM and a pair of 250G SATA2 disks, with everything except /boot inside an encrypted LVM partition (I'm using dm_crypt).
