ECC System Messages
ECC-1000
Message <timestamp>, [ECC-1000], <sequence-number>,, ERROR, <system-name>, ECC Error
<Multiple or single occurrence of errors of a given type detected> occurrence of
<Automatic calibration error detected> <Multiple bit error detected> <Single bit
error detected><Memory select error detected>.
Probable Cause Indicates that the processor memory controller has detected one of several types of DDR memory
errors. Single bit errors are corrected, but other errors indicate either software errors or problems
with the target system DRAM. Single bit errors can be expected to occur infrequently and can be
caused by uncontrollable external events like cosmic rays, but frequent single bit errors can be
indications of a degrading DRAM device.
Recommended
Action
Frequent single bit errors and all other error types should be reported to technical support for
further action.
Severity ERROR
ECC-1001
Message <timestamp>, [ECC-1001], <sequence-number>,, ERROR, <system-name>, ECC Error
<Multiple or single occurrence of multiple bit ECC error detected> <Multiple or
single occurrence of single bit ECC error detected> <Multiple of single occurrence
of access outside the defined physical memory space detected> detected.
Probable Cause Indicates that the processor memory controller has detected one of several types of DDR memory
errors. Single bit errors are corrected, but other errors indicate either software errors or problems
with the target system DRAM. Single bit errors can be expected to occur infrequently and can be
caused by uncontrollable external events like cosmic rays (I am not making that up!), but frequent
single bit errors can be indications of a degrading DRAM device.
