Hi guys, i've followed the "Ubuntu 9.10 Perfect Server Guide", and everything is fine. My Single problem is that the FTP Server goes down like every 2 days, and i have to restart it everytime . I dont know whats going on, could any one give me a hand on this? Im dissapointed about ubuntu 9.10 , my ispconfig servers running ubuntu 8.04 lts work like a charm from a year now.
all i got in syslog is Code: Mar 21 07:15:40 190-82-73-123 kernel: [505519.110037] ------------[ cut here ]------------ Mar 21 07:15:40 190-82-73-123 kernel: [505519.110044] WARNING: at /build/buildd/linux-2.6.31/fs/quota/dquot.c:964 dquot_claim_space+0x147/0x170() Mar 21 07:15:40 190-82-73-123 kernel: [505519.110046] Hardware name: Mar 21 07:15:40 190-82-73-123 kernel: [505519.110047] Modules linked in: ufs qnx4 hfsplus hfs minix ntfs vfat msdos fat jfs xfs exportfs reiserfs iptable_mangle iptable_nat nf_$ Mar 21 07:15:40 190-82-73-123 kernel: [505519.110083] Pid: 46, comm: pdflush Tainted: G W 2.6.31-20-server #57-Ubuntu Mar 21 07:15:40 190-82-73-123 kernel: [505519.110085] Call Trace: Mar 21 07:15:40 190-82-73-123 kernel: [505519.110089] [<ffffffff8105e538>] warn_slowpath_common+0x78/0xb0 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110093] [<ffffffff8105e57f>] warn_slowpath_null+0xf/0x20 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110096] [<ffffffff8116ee47>] dquot_claim_space+0x147/0x170 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110100] [<ffffffff811dd1cc>] ext4_mb_mark_diskspace_used+0x32c/0x380 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110103] [<ffffffff811deb59>] ext4_mb_new_blocks+0x2a9/0x560 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110107] [<ffffffff811d2cb0>] ? ext4_ext_find_extent+0x130/0x2f0 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110111] [<ffffffff811d51fa>] ext4_ext_get_blocks+0x45a/0x620 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110115] [<ffffffff81279cd5>] ? radix_tree_gang_lookup_tag_slot+0x95/0xe0 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110118] [<ffffffff811b4d91>] ext4_get_blocks+0x1e1/0x210 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110122] [<ffffffff811b5847>] mpage_da_map_blocks+0xa7/0x370 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110125] [<ffffffff811ed9be>] ? jbd2_journal_start+0xae/0x100 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110128] [<ffffffff811b5dd8>] ext4_da_writepages+0x2c8/0x5c0 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110132] [<ffffffff810e3168>] do_writepages+0x28/0x50 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110136] [<ffffffff8113eb5c>] writeback_single_inode+0x1bc/0x450 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110139] [<ffffffff8106ac80>] ? process_timeout+0x0/0x10 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110142] [<ffffffff8113f478>] generic_sync_sb_inodes+0x418/0x530 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110145] [<ffffffff8127a8d6>] ? rb_erase+0xd6/0x160 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110148] [<ffffffff8113f69b>] writeback_inodes+0x5b/0x100 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110151] [<ffffffff810e1efc>] wb_kupdate+0xbc/0x140 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110155] [<ffffffff810e396e>] __pdflush+0x13e/0x260 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110158] [<ffffffff810e3a90>] ? pdflush+0x0/0x50 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110161] [<ffffffff810e3ad8>] pdflush+0x48/0x50 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110164] [<ffffffff810e1e40>] ? wb_kupdate+0x0/0x140 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110167] [<ffffffff810e3a90>] ? pdflush+0x0/0x50 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110170] [<ffffffff81078116>] kthread+0xa6/0xb0 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110173] [<ffffffff810130ea>] child_rip+0xa/0x20 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110176] [<ffffffff81078070>] ? kthread+0x0/0xb0 Mar 21 07:15:40 190-82-73-123 kernel: [505519.110179] [<ffffffff810130e0>] ? child_rip+0x0/0x20 many times, i dont think that this has to be with the ftp daemon right?

But i'm not sure about the FTP daemon described by Timo. I think there is a bug in kernel.
