I get back from two weeks on the road, and try to VNC to my server and
it fails. I ssh in and see that, yes vncserver is dead. I tried
restarting it and see below for the failure messages plus my systemd setup.
Can someone point me to trouble shooting why it says about resources (if
that is the problem);

# cat /etc/systemd/system/vncserver@.service

# Quick HowTo:
# 1. Copy this file to /etc/systemd/system/vncserver@.service
# 2. Edit /etc/systemd/system/vncserver@.service, replacing <USER>
# with the actual user name. Leave the remaining lines of the file
unmodified
# (ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
# PIDFile=/home/<USER>/.vnc/%H%i.pid)
# 3. Run `systemctl daemon-reload`
# 4. Run `systemctl enable vncserver@:<display>.service`
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, you should
# limit connections to the local host and then tunnel from
# the machine you want to view VNC on (host A) to the machine
# whose VNC output you want to view (host B)
#
# [user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB
#
# this will open a connection on port 590N of your hostA to hostB's port
590M
# (in fact, it ssh-connects to hostB and then connects to localhost (on
hostB).
# See the ssh man page for details on port forwarding)
#
# You can then point a VNC client on hostA at vncdisplay N of localhost
and with
# the help of ssh, you end up seeing what hostB makes available on port 590M
#
# 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.
