Hello everyone, good night. Today I had a serious problem on my server. The operating system is ubuntu 10.10. The machine is HP DL120. I have 4 hard drives each with 1.5TB RAID1 +0 (software raid because this controller was not found in installation of ubuntu). I do not know why, but the machine crashed today 6:00 PM and returned after 30 minutes alone, without rebooting. The syslog messages are: Code: May 12 17:59:13 turbo CRON[21309]: (root) CMD (/usr/local/ispconfig/server/server.sh > /dev/null 2>> /var/log/ispconfig/cron.log) May 12 17:59:13 turbo CRON[21310]: (web92) CMD (/usr/bin/wget -q -O /dev/null 'http://marketing.macromind.com.br/admin/cron/cron.php' >/dev/null 2>&1) May 12 17:59:13 turbo pure-ftpd: ([email protected]) [INFO] New connection from 95.168.195.26 May 12 17:59:13 turbo pure-ftpd: ([email protected]) [INFO] New connection from 95.168.195.26 May 12 17:59:14 turbo postfix/smtpd[15021]: warning: problem talking to server private/policy: Connection timed out May 12 17:59:16 turbo postfix/smtpd[15021]: NOQUEUE: reject: RCPT from gwmail.bradescoseguros.com.br[189.57.226.93]: 451 4.3.5 Server configuration problem; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gwmail.bradescoseguros.com.br> May 12 17:59:21 turbo kernel: [3864359.578346] mysqld invoked oom-killer: gfp_mask=0x44d0, order=2, oom_adj=0 May 12 17:59:20 turbo pop3d: LOGIN FAILED, [email protected], ip=[::ffff:201.92.33.199] May 12 17:59:21 turbo kernel: [3864359.578349] mysqld cpuset=/ mems_allowed=0 May 12 17:59:21 turbo kernel: [3864359.578352] Pid: 20652, comm: mysqld Not tainted 2.6.35-28-server #49-Ubuntu May 12 17:59:21 turbo kernel: [3864359.578353] Call Trace: May 12 17:59:21 turbo kernel: [3864359.578360] [<ffffffff810af25d>] ? cpuset_print_task_mems_allowed+0x9d/0xb0 May 12 17:59:21 turbo kernel: [3864359.578364] [<ffffffff81104ba1>] dump_header+0x81/0xc0 May 12 17:59:21 turbo kernel: [3864359.578366] [<ffffffff81104c61>] oom_kill_process+0x81/0x180 May 12 17:59:21 turbo kernel: [3864359.578368] [<ffffffff81105198>] __out_of_memory+0x58/0xd0 May 12 17:59:21 turbo kernel: [3864359.578370] [<ffffffff81105296>] out_of_memory+0x86/0x1c0 May 12 17:59:21 turbo kernel: [3864359.578373] [<ffffffff81108cfe>] __alloc_pages_slowpath+0x58e/0x5a0 May 12 17:59:21 turbo kernel: [3864359.578375] [<ffffffff81108e7c>] __alloc_pages_nodemask+0x16c/0x1d0 May 12 17:59:21 turbo kernel: [3864359.578379] [<ffffffff81140aa2>] kmalloc_large_node+0x62/0xb0 May 12 17:59:21 turbo kernel: [3864359.578382] [<ffffffff8114459c>] __kmalloc_node_track_caller+0x11c/0x1d0 May 12 17:59:21 turbo kernel: [3864359.578385] [<ffffffff8105222a>] ? finish_task_switch+0x4a/0xd0 May 12 17:59:21 turbo kernel: [3864359.578388] [<ffffffff814a0514>] ? sock_alloc_send_pskb+0x1d4/0x340 May 12 17:59:21 turbo kernel: [3864359.578391] [<ffffffff814a4763>] __alloc_skb+0x83/0x170 May 12 17:59:21 turbo kernel: [3864359.578393] [<ffffffff814a0514>] sock_alloc_send_pskb+0x1d4/0x340 May 12 17:59:21 turbo kernel: [3864359.578397] [<ffffffff8159fb22>] ? io_schedule+0x92/0xc0 May 12 17:59:21 turbo kernel: [3864359.578399] [<ffffffff814a0695>] sock_alloc_send_skb+0x15/0x20 May 12 17:59:21 turbo kernel: [3864359.578402] [<ffffffff8153903b>] unix_stream_sendmsg+0x33b/0x430 May 12 17:59:21 turbo kernel: [3864359.578405] [<ffffffff81103068>] ?

What are these errors? Please, what should I do to eliminate this error? Thanks.
Hello again. I am reading about fake raid. Likely my fault: Do not have a swap partition created. I can create a swap partition on a system already installed on fake raid? Thanks.
I'm running the following commands: Code: root@turbo:/# dd if=/dev/zero of=/swapRaid bs=1024 count=4194304 root@turbo:/# chmod 600 /swapRaid root@turbo:/# mkswap swapRaid mkswap: swapRaid: warning: don't erase bootbits sectors no disco inteiro. Use -f to force. Setting up swapspace version 1, size = 4194300 KiB no label, UUID=1b3ad17b-23d0-4a3b-bb61-a05c1429d4bc root@turbo:/# I will have problems if you continue with: Code: swapon swapRaid on fake raid??? Thanks
No errors Code: root@turbo:/# swapon swapRaid root@turbo:/# free -m total used free shared buffers cached Mem: 3954 3082 872 0 48 283 -/+ buffers/cache: 2750 1204 Swap: 4095 0 4095 Now, I'll follow up and see the performance of the server. I want to end slowness and errors such as today. I hope to help someone with this post.
