Most of the servers I administer are behind a load balancer just like yours and they come out of a pool when they are acting up. However, what I tend to do (for tomcat applications for example) is get a thread dump of what the application is doing at the time, get all the logs, as well as what processes including memory/cpu usage are running on the system. I then use this to debug it. If this is a single point of failure I go for the quick restart after collecting as much data as possible.
Our uptime is managed by service availability, but our SLA's include hosts/services on those hosts. So I am required to respond to them even if the service is still functioning properly.

I had a doubt if any services need to be restarted if port no in /etc/services in an RHEL setup is changed. For eg, the port no of 443 for SSL may need to be changed.

ypinit
ypinit(1M) System Administration Commands ypinit(1M)
NAME
ypinit - set up NIS client
SYNOPSIS
/usr/sbin/ypinit [-c] [-m] [-s master_server]
DESCRIPTION
ypinit can be used to set up an NIS client system. You must be the superuser to run this command. This script need not be used at all if
ypbind(1M) is started with the -broadcast option (it is invoked with this option from the svc:/network/nis/client:default service).
Normally, ypinit is run only once after installing the system. It may be run whenever a new NIS server is added to the network or an
existing one is decommissioned.
ypinit prompts for a list of NIS servers to bind the client to; this list should be ordered from the closest to the furthest server. Each
of these NIS servers must be listed in either the /etc/hosts or the /etc/inet/ipnodes file along with its IP address. ypinit stores the
list in file /var/yp/binding/domain/ypservers. This file is used by ypbind when run without the -broadcast option.
OPTIONS
-c Set up a ypclient system.
-m Build a master ypserver data base.
-s master_server Slave data base. master_server must be the same master configured in the YP maps and returned by the ypwhich -m
command.
FILES
/etc/hosts
/etc/inet/ipnodes
/var/yp/binding/domain/ypservers

SEE ALSO
svcs(1), svcadm(1M), ypbind(1M), sysinfo(2), hosts(4), ipnodes(4), attributes(5), smf(5)
NOTES
The NIS client service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/nis/client:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
BUGS
ypinit sets up the list of NIS servers only for the current domain on the system when it is run, that is, the domain returned by the
SI_SRPC_DOMAIN command to sysinfo(2). Care should be taken to ensure that this is the same as the desired domain for NIS client processes.
