VNCServer - Xvnc dead but subsys locked

Question

Environment:
Oracle Linux Server release 6.5
Linux version 2.6.39-400.215.3.el6uek.x86_64 ([email protected]) (gcc version 4.4.6 20110731 (Red Hat 4.4.6-3) (GCC) ) #1 SMP Fri Jun 20 00:37:05 PDT 2014
I attempted to configure vncserver.  First I ran 11gr2 pre-install package from Oracle.  Later, we decided to go with 12c so I ran 12cR1 pre-install package.  I performed a yum update.  I configured the vncserver with the procedure below.  I get the following error message, "Xvnc dead but subsys locked." when # service vncserver status.  It starts working but fails within seconds.  The normal sys admin is on vacation and I am fairly limited in linux troubleshooting.
# rpm -qa |grep vnc
tigervnc-1.1.0-8.el6_5.x86_64
tigervnc-server-1.1.0-8.el6_5.x86_64

# /usr/sbin/useradd -u 600 -d /home/grid -g oinstall -G asmadmin,asmdba,asmoper,dba -m -s /bin/bash grid

Make the following changes and additions to /etc/sysconfig/vncservers:
# vi /etc/sysconfig/vncservers
# The VNCSERVERS variable is a list of display:user pairs.
# Uncomment the lines below to start a VNC server on display :2
# as my 'myusername' (adjust this to your own).  You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted!  For a secure way of using VNC, see this URL:
# http://kbase.redhat.com/faq/docs/DOC-7028
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel.  See the "-via" option in the
# `man vncviewer' manual page.
# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
VNCSERVERS="2:grid 3:oracle"
VNCSERVERARGS[2]="-geometry 1024x768 -nolisten tcp"
VNCSERVERARGS[3]="-geometry 1024x768 -nolisten tcp"
# service vncserver start
# service vncserver stop
# chkconfig vncserver on
# service vncserver status
Xvnc (pid 19361 19292) is running...
# service vncserver status
Xvnc dead but subsys locked

Answer 1

I am not using the client to connect yet.  The service displays a failure.  I checked one of the users that should be started when the service vncserver start command is executed and I show the following error message in /home/<user>/.vnc/<fqhn>:2.log:
vncconfig: unable to open display "<fqhn>:2"
xrdb: Connection refused
xrdb: Can't open display '<fqhn>:2'
xmodmap:  unable to open display '<fqhn>:2'
mkdtemp: private socket dir: Permission denied
Fatal server error:
Could not create lock file in /tmp/.tX2-lock
Note: Substituted Fully Qualified Host Name (fqhn) and user in <>.
It seems that I needed to change the permissions on my /tmp directory.
drwxrwxr-x.   6 root root      4096 Jul  2 08:18 tmp
chmod 1777
drwxrwxrwt. 22 root root 4096 Jul  2 09:01 /tmp
It seems to be working now.  Thank you for your help.
