Hi,
I’ve got a memory issue.
SLES seems to be incorrectly reporting memory.
The machine has 4GB and this is indicated in the boot.msg:
<7>[ 0.000000] ACPI: Local APIC address 0xfee00000
<6>[ 0.000000] No NUMA configuration found
<6>[ 0.000000] Faking a node at 0000000000000000-0000000100600000

<5>[ 0.000000] 3220MB HIGHMEM available.
<5>[ 0.000000] 881MB LOWMEM available.
However when doing a free, it only shows around 1.8GB :
linux3:/ # free -l
total used free shared buffers cached
Mem: 1822060 578912 1243148 0 12480 533132
Low: 775100 226448 548652
High: 1046960 352464 694496
-/+ buffers/cache: 33300 1788760
Swap: 2103292 15648 2087644
I get out of memory errors beyond the 1.8GB
Anyone got any ideas ?
How do I reconfigure so that the full 4GB is reflected ?
Regards
Steven

What does:
uname -a
cat /proc/meminfo
Show?

What make/brand is the server? And are the memory chips all of the same type?
Could be something with the BIOS. Maybe check for and apply the latest BIOS for the main board, or not already done so.
