Hi all, We have a test version of ISPConfig running on Debian 3.1 with php 5 from backports. It is running in a domU on a virtualised Xen server. We want to take the site live and already have one of our sites running on it to test. On a regular basis we get the following error page when trying to login to ispconfig which tell us to run "mysqladmin flush hosts" as there has been to many dropped connection from the relevant ip. (Sorry I cant remember the full message now and I have just flushed mysql.) I also noticed the following in dmesg Code: oom-killer: gfp_mask=0x201d2, order=0 [<c0141f21>] out_of_memory+0x161/0x180 [<c0143aed>] __alloc_pages+0x26d/0x2d0 [<c014591a>] __do_page_cache_readahead+0x14a/0x300 [<c01a6950>] ext3_get_block+0x0/0xc0 [<c03450f8>] io_schedule+0x28/0x40 [<c034593b>] __wait_on_bit_lock+0x5b/0x70 [<c013e1d0>] sync_page+0x0/0x50 [<c01457ad>] max_sane_readahead+0x2d/0x50 [<c01413fe>] filemap_nopage+0x2ee/0x3e0 [<c014bedf>] __handle_mm_fault+0x16f/0xc00 [<c012610c>] try_to_del_timer_sync+0x4c/0x60 [<c0126138>] del_timer_sync+0x18/0x20 [<c0143384>] free_hot_cold_page+0x114/0x1b0 [<c0174ad4>] poll_freewait+0x44/0x60 [<c0111840>] do_page_fault+0x4a0/0x7ac [<c01113a0>] do_page_fault+0x0/0x7ac [<c0105273>] error_code+0x2b/0x30 Mem-info: DMA per-cpu: cpu 0 hot: high 90, batch 15 used:11 cpu 0 cold: high 30, batch 7 used:28 DMA32 per-cpu: empty Normal per-cpu: empty HighMem per-cpu: empty Free pages: 2348kB (0kB HighMem) Active:30152 inactive:30122 dirty:0 writeback:0 unstable:0 free:587 slab:2234 mapped:60257 pagetables:413 DMA free:2348kB min:2076kB low:2592kB high:3112kB active:120608kB inactive:120488kB present:270336kB pages_scanned:187350 all_unreclaimable? no lowmem_reserve[]: 0 0 0 0 DMA32 free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 0 Normal free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 0 HighMem free:0kB min:128kB low:128kB high:128kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 0 DMA: 71*4kB 4*8kB 1*16kB 1*32kB 1*64kB 1*128kB 1*256kB 1*512kB 1*1024kB 0*2048kB 0*4096kB = 2348kB DMA32: empty Normal: empty HighMem: empty Swap cache: add 260371, delete 260371, find 21451/25337, race 0+0 Free swap = 0kB Total swap = 511992kB Free swap: 0kB 67584 pages of RAM 0 pages of HIGHMEM 1604 reserved pages 298 pages shared 0 pages swap cached 0 pages dirty 0 pages writeback 60257 pages mapped 2234 pages slab 413 pages pagetables Out of Memory: Kill process 557 (ispconfig_httpd) score 30974 and children.
