(Doc ID 1995167.1)

Last updated on APRIL 16, 2015

Applies to:

Linux OS - Version Oracle Linux 6.0 and later
Linux x86-64


Running Oracle RDBM PSU4 and CRS on Oracle Linux 6.6 and when instance starts and mounted orarootagent.bin uses a large amount of CPU and also high load.

The issue could be reproduced with UEK2/UEK3/RHCK when Oracle instance is started and DB is mounted.

Due to this issue, lot of CPU and load on the system is extremely high, cannot run the database.
