Node evictions in RAC environment are quite common and there are
variety of reasons than can cause this. You should read and follow this
article on Metalink - Troubleshooting ORA-29740 in a RAC Environment
(Note:219361.1), especially important is the eviction reason from LMON
tracefile. With this information you should be able to narrow the
search. The reason for eviction could be either problem in your
environment (network issues with interconnect, cluster problems etc.)
or Oracle bugs such as 4031502 (there is the patch for this one).
