Detailed discussion on Node eviction errors in RAC environments.

Reason 0 = No reconfiguration
Reason 1 = The Node Monitor generated the reconfiguration.
Reason 2 = An instance death was detected.
Reason 3 = Communications Failure
Reason 4 = Reconfiguration after suspend
Important files to review are:
a) Each instance's alert log
b) Each instance's LMON trace file
c) Statspack reports from all nodes leading up to the eviction
d) Each node's syslog or messages file
e) iostat output before, after, and during evictions
f) vmstat output before, after, and during evictions
g) netstat output before, after, and during evictions
