And that mistake is where?  I have a feeling that is the $64K question.

>Are you running thousands of httpd or other processes?

No, according to htop, the single start of httpd is running 9 instances total 
which ISTR is normal from previous observation.  This is booted to 2.6.30.1.  
htop says 662/4052 megs of memory, with the red bar extending to maybe the 3G 
mark when booted to this 2.6.30.1 kernel.

The above shows more httpd's than were running normally.  Does it start 
another instance to service a request?  My httpd server is only accessable to 
the net via a port forward in dd-wrt, so it isn't something a drive-by would 
normally find.

gkrellm shows about 316 processes running with 17 users, all of whom are 
either system or related to me (I'm the only real user but delegate some 
things to normal users, like mail fetching etc), and I don't recall seeing any 
noticeably larger values when 31-rc2 was running, at least not early in the 
run.  The oom deaths were all at times when I wasn't present.

But that rebuilt 31-rc2 also died in about 12 hours due to oom, as I posted 
later.

At least CONFIG_HIGHMEM64G is not necessary, could try disabling it.

I'm wondering why the same bug didn't turn up in earlier kernels.
Can you post the full .config, dmesg, /proc/zoneinfo and /proc/meminfo?

Thanks for the details. It seems that the OOM is not likely caused by
too much processes doing concurrent reclaims.

I have in a rebuild of this 2.6.30.1 kernel, but ISTR I enabled that because 
it was only using 3G of the 4G of ram in this box, an AMD-64 Phenom, 4 cores, 
4G ram.  But I haven't rebooted to it yet.  Next good excuse.  See below... :)

I guess you can only use 3G ram because there is a big memory hole.
Your HighMem zone spanned 951810 pages, 813013 of which is present.
So it's not quite accurate for the OOM message "951810 pages HighMem"
to report the spanned pages.

Your Normal zone has 221994 present pages, while the OOM message shows
"slab:206505", which indicates that the OOM is caused by too much
slab pages(they cannot be allocated from HighMem zone).

I guess your near 800MB slab cache is somehow under scanned.

Thanks,
Fengguang

Gene, can you run .31 with this patch? When OOM happens, it will tell
us whether the majority slab pages are reclaimable. Another way to 
find things out is to run `slabtop` when your system is moderately loaded.

Thanks,
Fengguang

Subject: [PATCH] add per-zone statistics to show_free_areas()

Currently, show_free_area() mainly display system memory usage. but it
doesn't display per-zone memory usage information.

However, if DMA zone OOM occur, Administrator definitely need to know
per-zone memory usage information.

Yes, as of 9:55am this patch is running, and I have a session of slabtop (and 
although it is old, it is a new one to me, so I'm not sure what a normal 
report should look like) running.

This is also without the HIGH_MEM64G, so I only have about 3.5G of ram 
showing.

There is one line early in the dmesg that needs clarified:

[    0.000000] TOM2: 0000000120000000 aka 4608M

that is more memory than is in the machine unless its somehow counting the DDR 
ram on the video card, and IIRC that is only 256megs in any event.  Swap is 
not mounted by that point, much later.

Also from this dmesg:
[    0.000000] On node 0 totalpages: 917103
[    0.000000] free_area_init_node: node 0, pgdat c13f5400, node_mem_map 
c14bf200
[    0.000000]   DMA zone: 32 pages used for memmap
[    0.000000]   DMA zone: 0 pages reserved
[    0.000000]   DMA zone: 3951 pages, LIFO batch:0
[    0.000000]   Normal zone: 1744 pages used for memmap
[    0.000000]   Normal zone: 221486 pages, LIFO batch:31
[    0.000000]   HighMem zone: 5390 pages used for memmap
[    0.000000]   HighMem zone: 684500 pages, LIFO batch:31
==================
is this correct?

From slabtop right now:

Minimum / Average / Maximum Object : 0.01K / 0.24K / 4096.00K
=================
Humm, that is running in an x terminal, I'll start one on tty2 also.
I might have a better chance of seeing it after x dies.

FWIW, 2.6.30.1, also built w/o that 64G flag, and with the newest bios, also 
ran all night, which surprised me.  I half expected to wake up to a dead 
machine.  I have every time I installed that bios before...

Now we wait...  Thanks, Fengguang

To Wu Fengguang, David H., Rafael W., lkml:

With this patch, the newest bios for this board, and without the 
CONFIG_HIGHMEM64G in the config, 2.6.31-rc2 has achieved a full days uptime.
I did do a swapoff -a; swapon -a about an hour into the boot to zero the swap, 
and in nearly 24 hours it hasn't used any.  No oom's that I can find in the 
logs.

If the 64G highmem option, and this bios meet on this machine, the crash is at 
least 20 hours overdue.  But it appears to be 100% normal yet.

My opinion is that the 64G, long address memory handling may be broken 
somewhere.  Running w/o it costs me about half a gig of ram, but in this case, 
the loss is well worth it.

What is the reason that setting the 4G of memory option results in only 
approximately 3.5G being shown again?

Many Thanks to all of you, I have a stable machine now.

Just wondering, is this your M2N-SLI Deluxe board?  I've got the same
board, with 4Gb of RAM and I haven't noticed any loss of RAM from my
looking (quickly) at top output.

But I also haven't bothered to upgrade the BIOS on this board at all
since I got it back in March of 2008.  No need in my book so far.

I had been running the original bios, #1502, because 1604 and 1701 had very 
poor uptimes.  1502 caused an oops about 15 lines into the boot but that 
triggered a remap and it was bulletproof after that running a 32 bit 64G+PAE 
kernel.  (I haven't quite made the jump to a 64 bit install, yet...)

Why haven't you made the laep to 64bit yet?  To me, that seems to be
the real solution here, not hacks like the HIGHMEM4G and HIGHMEM64G,
esp when your hardware is 64Bit by default.  

I've made the leap and I've never looked back.  Haven't missed any
32bit only apps, and if I really needed them, I'd just load the 32bit
libraries if need be.

Sure 64bit kernel would be the best option for Gene :)

But for now I'd appreciate a lot if Gene can run a HIGHMEM64G kernel
with the provided patch, so as to collect one full OOM message for us
to analyze :) The previous OOM message missed the most important data
from zone Normal..

Most relevant ones:

- 300+MB >4G memory is not reachable by kernel and user space
- 2.7GB high memory is not usable for slab caches and some other
  kernel users

In theory the SLAB pages can mostly be reclaimed when memory is tight.
So your OOM happens either because the SLAB pages are not reclaimable,
or the reclaim algorithm didn't reclaim them as much as it should.

slabtop does output something, and then the screen get cleared
immediately. It seems related to the alternate screen concept,
xterm has a resource 'titeInhibit' for it. Though I'm not sure
how the slabtop code can be fixed in a trivial way.

Hmm not likely caused by amanda. It can use the HighMem pages so you
didn't see OOM when amanda uses up to 3G buffers.

Don't be in a hurry. Just enjoy the current good state until OOM revisits :)

Its been about 3d 10h of uptime now, and its been boringly stable.  Darn it.

Memory usage ack to htop has about doubled (to 828 megs from 385 or so 
originally), and its 24MB into swap, so I'd assume there is a small leak 
somewhere.  At this rate it will take weeks to trigger this again.

I've now built 2.6.31-rc3 with pretty much the same options re: memory, and 
will probably reboot to it in the morning as its approaching the witching hour 
here.  Any objections?
