Hi,
one more addition:
I used mysqldump to dump some big database, and here's something weird:
jerboas:/mnt# ls -la
total 372024
drwxr-xr-x 2 root root 80 Sep 19 16:34 .
drwxr-xr-x 20 root root 4096 Sep 19 11:32 ..
-rw-r--r-- 1 root root 380946064 Sep 19 16:35 Celegans.sql
jerboas:/mnt# ls -la
ls: Celegans.sql: Value too large for defined data type
total 4
drwxr-xr-x 2 root root 80 Sep 19 16:34 .
drwxr-xr-x 20 root root 4096 Sep 19 11:32 ..

Running `mc' in this directory says:

It's on freshly made reiserfs filesystem, if it helps.

(multiple files). In the /mnt it should the dump be all in one file, also
on reiserfs. The machine has 1GB RAM, SMP kernel, HIGHMEM enabled.

Impossible, the VM code which is in 2.4.10-pre11 and newer
wasn't published until sunday night, so you can't have been
using it for a week already. ;)

Sorry, again: I'm currently using plain 2.4.9 patched with -pre12.
I get the allocation errors. I got the image from kernel.dk/testing/ today
morning, as someone posted this address on the list.
My previous kernel is plain 2.4.9 patched with Marcelo's patched and in a
week period I did not receive nay single error message like that.

After some stress testing, the fix does appear to fix the
error.

did it happen as frequently/easily as before or did you need to stress
it much harder? And I'm also curious what happens if we simply lower the
watemark (possibly it was too high). Anyways the other patch is a good
idea to apply anyways.
So can now try the below new one?

the fact is, kswapd is the only entity meant to shrink the caches for
the atomic pages, it exactly knows what are the zones that needs to be
balanced and we have a min-min/2 of pages of GAP that must be refilled
in time. It just seems kswapd doesn't cope with the frequency of the
allocations sometime, this may be ok but maybe we must find a way to
more aggressively free memory for the atomic allocations or it could
simply mean that the watermark GAP was too small as Marcelo just
suggested previously.
Can you also resolve "c012e052" so we know who's allocating those pages
just in case?

It's trivial to do that, of course, but if someone needs an
automated way to do it (several times, easy lookup), you can
try http://www.osdlab.org/sw_resources/scripts/ksysmap .
Usage is: ksysmap [system_map_file] offset
and it spits out address/symbol before offset, exact match if
present, and address/symbol after offset.
Example:
[rddunlap@dragon linux]$ ksysmap ./System.map-249acpi c012e052
ksysmap: searching './System.map-249acpi' for 'c012e052'
c012df20 T sys_truncate
c012e052 ..... <<<<<
c012e0a0 T sys_ftruncate

Idea pinched for ksymoops 2.4.3; ksymoops -A "address list", any words
in the -A list are treated as addresses and looked up in the composite
system map, including modules.

Hi,
first of all, thanks to Andrea. I had a bit hard time to find sources of
his kernel-patches.
Note to the FAQ maintainer: there isn't mentioned the source for -ac and
-aa kernels.
I found that I need 2.4.9 patched to -pre12 and patched afterwards with
http://www.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.10pre12aa1.bz2
Using my old configuration for kernel I get after "make dep; make bzImage"

There are two defines for that FPU thing around line 421 in sched.c, take
one away (i deleted the 1<<6 one).
I'm running that kernel now.

Hi,
I've just started some tests to try to repeat the memory allocation
errors. I see the aa1 kernel is twice fast as -pre12!? Is this expected?
I have 2x intelPIII 933MHz, 1GB RAM, HIGMEM kernel, ReiserFS, aic7xxx,
eepro100.

dbench 16: Throughput 67.8566 MB/sec (NB=84.8208 MB/sec 678.566 MBit/sec) 16 procs
Yesterday after havy tests and after memory alloc. errors already
appeared:

The documentation to dbech is a bit sparse (README,INSTALL). It's a bit
offtopic, but would someone explain me where does the dbench write, into
which directory? I performed the tests above under same user and in same
tmp/ directory, to be sure. Maybe it was not necessary at all. ;)
Thanks

Hmm, now after few ours of running mysql tests I have (while still running):
linux-2.4.10-pre12aa1
dbench 16: Throughput 41.1484 MB/sec (NB=51.4356 MB/sec 411.484 MBit/sec) 16 procs
Load so far up to 7 (yesterday even 16, but thatt dependes of course while
test is currently being run).
And, well oh NO!, it's here again:
__alloc_pages: 0-order allocation failed (gfp=0x20/0) from c012f852
How can I find what mean those (gfp=0x20/0) from c012f852 ?

People,
As I'm sure you're all aware, being experts in userland programming, that
the above obviously cannot work and is totally bogus.
The mkversion script contains:
if [ ! -f .version ]
then
echo 1
else
expr 0`cat .version` + 1
fi
but wait! As far as the script is concerned, .version will always exist
because its created before the script is run (the open occurs, the file is
truncated, and passed to the script as STDOUT).
This has a nice effect - the build number of the kernel is now fixed at '1'.
So, why don't we get rid of the above crap and just do "echo 1 > .version"
and be done with it? ;)
Alternatively, the following patch fixes things such that we can read the
original .version file within the script, if it existed prior to invocation,
and produce the correct build number.
Note that as illustrated by the previous poster, -linus now has the problem,
and -ac also has the same. The following patch was generated against
2.4.9-ac10, but should apply to both trees without problem.

Ok, I'm pretty certain I got it, I didn't noticed here because it can be
reproduced only with HIGHMEM and I didn't had time to test highmem yet
(btw, highmem emulation would been enough to reproduce it).
It was really an allocator bug. Totally untested fix appended
but recommended anyways for integration.
Marcelo can you also test it in your workload (feel free to use eepro100
too now).
