(Doc ID 725951.1)
Last updated on FEBRUARY 14, 2022
Applies to:
Oracle Database - Enterprise Edition - Version 10.2.0.4 to 10.2.0.4 [Release 10.2]Information in this document applies to any platform.
Symptoms
This issue was observed on Oracle 10.2.0.4 64-bit on a Enterprise Manager repository database.
Symptoms
-------------
In this case, the problem showed up as many spawned perl processes on the server, not on the repository. Disabling the EM agent stopped the problem.
The alert log on the Enterprise manager repository shows the error, and it is preceded by a Controlfile timeout:
Killing enqueue blocker (pid=23270) on resource CF-00000000-00000000 by killing session 151.1
ORA-07445: exception encountered: core dump [ksuklms()+527] [SIGSEGV] [Address not mapped to
object] [0x000000062] [] []
The trace file may show a failing statement similar to this:
begin sys . dbms_backup_restore . commitRmanStatusRow
( row_id => :row_id , row_stamp => :row_stamp , mbytes => :mb , status => :status ,
ibytes => :ib , obytes => :ob , odevtype => :odevtype ) ;
end ;
The trace file will also show a Controlfile timeout :
ORA-00494: enqueue [CF] held for too long (more than 900 seconds) by 'inst 1, osid 23270
This traces to PID 23274
service name: SYS$BACKGROUND
waiting for 'Streams AQ: qmn coordinator idle wait'
