On my 11.2&2 node RAC system, one of the node has been rebooted. While I was investigating issue I noticed LMDO process terminating the instance.
We have below in alert.log on victim node:
LMS2 (ospid: 28770960) received an instance eviction notification from instance 2 [2] LMON received an instance eviction notification from instance 2 The instance eviction reason is 0x2 The instance eviction map is 1 PMON (ospid: 13435162): terminating the instance due to error 481 /oracle11g/db/diag/rdbms/VIS/rac_node1/trace/rac_node1_diag_19530038.trc
