Dcache ECC error on cpu0
with
8 GByte RAM with the following memory organisation:
0 2048Mb 0000000000000000 4-Way
1 2048Mb 0000000080000000 4-Way
2 2048Mb 0000000100000000 4-Way
3 2048Mb 0000000180000000 4-Way
After one year of running a few weeks ago the following messages appear
in the syslog:
Jul 22 16:12:15 ragnaroek vmunix: WARNING: too many Processor corrected
errors detected on cpu 2. Reporting suspended.
Jul 22 16:13:27 ragnaroek vmunix: WARNING: too many Processor corrected
errors detected on cpu 1. Reporting suspended.
Jul 22 16:14:18 ragnaroek vmunix: WARNING: too many Processor corrected
errors detected on cpu 3. Reporting suspended.
and a few hours later the machine goes to the console prompt.
During the memory test the following messages appear:
EV6 Correctable Memory Fill ECC Error on CPU 0
C_ADDR: 00000000A8FC5BC0
C_SYNDROME_1: 0000000000000057
C_SYNDROME_0: 0000000000000000
EV6 Correctable Dcache ECC Error on CPU 0
EV6 Correctable Memory Fill ECC Error on CPU 0
C_ADDR: 00000000A8FD2BC0
C_SYNDROME_1: 0000000000000057
C_SYNDROME_0: 0000000000000000
First, I thought, it's an defect DRAM module, located in bank 1 because
of the
C_ADDR information. But after removing bank the error still occurs.
So, my question, it is a memory or CPU problem, and, if it's a memoery
problem,
how can I determine the defect DRAM Chip? I haven't found any suitable
documentation.

Re: Dcache ECC error on cpu0
it may be a cpu fault as well. If you do not have a maintenance contract, you should replace cpu 0 with cpu 3 and restart the machine.
greetings,
Michael

Re: Dcache ECC error on cpu0
your problem is memory, but to determine which dimm, please send to me the binary.errlog file of your ES40 Machine.
