      Description

      node = ts27 (x86_64)
      kernel = 2.6.18-92.1.13.el5.028stab059.1 #1 SMP Tue Sep 30 21:58:19 MSD 2008
      vzctl-lib-3.0.22-1
      vzctl-3.0.22-1
      bash-3.2-21.el5
      grep-2.5.1-54.2.el5

      1. Restarted OpenVZ and got this "error: Broken pipe":
      [root@ts27 ~]# /sbin/service vz restart
      Stopping OpenVZ: [ OK ]
      /etc/init.d/vz: line 200: echo: write error: Broken pipe
      /etc/init.d/vz: line 200: echo: write error: Broken pipe
      Starting OpenVZ: [ OK ]
      Bringing up interface venet0: [ OK ]
      Configuring interface venet0: [ OK ]

      2. This is the piece of /etc/init.d/vz, line 200 is marked:


      {
              test -r /proc/config.gz || return 0

              local conf opt err=0
              local opt_must="SIM_FS VE VE_CALLS VZ_GENCALLS"
              get_kernel_version
              # For kernels >= 2.6.9 VZ_DEV must be set.
              test "${KERNEL_MINOR}" -ge 6 &&
                      test "${KERNEL_PATCHLEVEL}" -gt 9 &&
                              opt_must="${opt_must} VZ_DEV"
              local opt_rec="SCHED_VCPU FAIRSCHED VZ_QUOTA VZ_QUOTA_UGID VE_NETDEV VE_ETHDEV
                              VE_IPTABLES VZ_CHECKPOINT VZ_WDOG"

              conf="`zcat /proc/config.gz 2>/dev/null | grep -E -v '^#|^$'`"

              for opt in $opt_must; do
                      if ! echo "${conf}" | grep -q "${opt}="; then # <-- LINE 200
                              echo "ERROR: Missing kernel config option: CONFIG_$opt"
                              err=1
                      fi
              done
              if [ $err != 0 ]; then
                      print_failure "Please recompile your kernel."
                      exit 1
              fi
      }

      3. This bug doesn't reproduces each time when OpenVZ is restarted, but it does pretty often, say 3 times out of 5.
