Server crash frequently
type: item
description: Hi all, We have used RHEL5 with OpenVZ 2.6.18 for long time. And now we started to use RHEL6 with OpenVZ 2.6.32 2 months ago, during these 2 months the server restarted automatically over 10 times. We are thinking whether the Memory/Swap are used out to cause the problem, however even we set the SWAPPAGES="0:0" (I guess this can disable SWAP), the server still restarts automatically. Below are information that may help to find out what's wrong, you may see the server restarted on Oct 12 11:09:57 and there are some kernel log around 11:00 that relates to Out of memory to kill process, but I think Out of memory should break down then container, but not the hardware node. Thanks in advance for any help OS: RHEL 6.0 OpenVZ Versions: vzquota-3.0.12-1.x86_64 vzkernel-firmware-2.6.32-042stab037.1.noarch vzkernel-2.6.32-042stab037.1.x86_64 vzctl-3.0.29.3-1.x86_64 vzctl-lib-3.0.29.3-1.x86_64 /etc/sysconfig/vz-scripts/101.conf: ========================================================= ONBOOT="yes" # UBC parameters (in form of barrier:limit) PHYSPAGES="0:2G" SWAPPAGES="0:0" KMEMSIZE="unlimited" LOCKEDPAGES="unlimited" PRIVVMPAGES="unlimited" SHMPAGES="unlimited" NUMPROC="unlimited" VMGUARPAGES="2G:unlimited" OOMGUARPAGES="2G:unlimited" NUMTCPSOCK="unlimited" NUMFLOCK="unlimited" NUMPTY="unlimited" NUMSIGINFO="unlimited" TCPSNDBUF="unlimited" TCPRCVBUF="unlimited" OTHERSOCKBUF="unlimited" DGRAMRCVBUF="unlimited" NUMOTHERSOCK="unlimited" DCACHESIZE="unlimited" NUMFILE="unlimited" NUMIPTENT="unlimited" # Disk quota parameters (in form of softlimit:hardlimit) DISKSPACE="500G:500G" DISKINODES="5000000:5050000" QUOTATIME="0" QUOTAUGIDLIMIT="1000" # CPU fair scheduler parameter CPUUNITS="50000" OSTEMPLATE="centos-4-i386-default" NAMESERVER="xxxxxxxxxxxxxxxx" CPULIMIT="50" VE_ROOT="/vz/root/$VEID" VE_PRIVATE="/vz/private/$VEID" ORIGIN_SAMPLE="vps.centos4" IP_ADDRESS="xxxxxxxxxxxxxxxx" HOSTNAME="xxxxxxxxxxxxxxxx" IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport…
