ERROR:
ORA-600 [17182] [a] [b] [c] [d] [e]
VERSIONS:
versions 7.0 to 9.2
DESCRIPTION:
Oracle has detected that the magic number in a memory chunk header has been
overwritten.
This is a heap (in memory) corruption and there is no underlying data
corruption.
The error may occur in the one of the process specific heaps
(the Call heap, PGA heap, or session heap) or in the shared heap (SGA).
FUNCTIONALITY:
HEAP MANAGEMENT
IMPACT:
PROCESS FAILURE
MEMORY CORRUPTION, POSSIBLE INSTANCE FAILURE.
NON DATA CORRUPTIVE - No underlying data corruption.
SUGGESTIONS:
Check to see if the issue is reproducable.
Check the OS system logs (/var/adm/messages on Solaris, for example)
for any memory corruption and run low level memory tests on the system.
If reproducable, send alert.log and trace files to support.
