I hope the community can help me ...
My problem is that if the resources are on either server, over a period
of 6 to 9 hours the web traffic begins to drain to zero while I am monitoring
it using the command:
ipvsadm -L --rate
I do not get an errors in /var/log/ha-debug or /var/log/ha-log. Something is
wrong with the configuration, but I cannot determine what is wrong with it.
Also, failover works sometimes and the for some reason LVS has an affinity with
LVS2 and not LVS1.
Any help would be much appreciated ...

# There are lots of options in this file. All you have to have is a set
# of nodes listed {"node ...}
# and one of {serial, bcast, mcast, or ucast}
#
# ATTENTION: As the configuration file is read line by line,
# THE ORDER OF DIRECTIVE MATTERS!
#
# In particular, make sure that the timings and udpport
# et al are set before the heartbeat media are defined!
# All will be fine if you keep them ordered as in this
# example.

#
# Note on logging:
# If any of debugfile, logfile and logfacility are defined then they
# will be used. If debugfile and/or logfile are not defined and
# logfacility is defined then the respective logging and debug
# messages will be loged to syslog. If logfacility is not defined
# then debugfile and logfile will be used to log messges. If
# logfacility is not defined and debugfile and/or logfile are not
# defined then defaults will be used for debugfile and logfile as
# required and messages will be sent there.

# On some machines/OSes, etc. the network takes a while to come up

# The default is "off", which means that it WILL fail

# "on" means that resources only move to new nodes when
# the nodes they are served on die. This is deemed as a

# read from a configuration file. The format of this line is:

# NOTE: it is up to you to maintain this file on each node in the

# STONITH support
# You can configure multiple stonith devices using this directive.
# The format of the line is:
# stonith_host <hostfrom> <stonith_type> <params...>
# <hostfrom> is the machine the stonith device is attached
# to or * to mean it is accessible from any host.
# <stonith_type> is the type of stonith device (a list of
# supported drives is in /usr/lib/stonith.)
# <params...> are driver specific parameters. To see the
# format for a particular device, run:
# stonith -l -t <stonith_type>
#
#
# Note that if you put your stonith device access information in
# here, and you make this file publically readable, you're asking
