Default Bug#611622: linux-image-2.6.32-bpo.5-686: VM problems

Package: linux-2.6
Version: 2.6.32-30~bpo50+1
Severity: normal


I keep getting VM failure messages. I suspect the machine
is simply a bit too slow for the network card which is in
it. It is a via Nehemia at 1.7GHz with an extra Intel
GigE server adapter. The backtraces look like showing
problems in the network receive/xmit routines.

The machine is swapless and is used mostly as an NFS
server. It was not showing this behaviour under 2.6.26

Best Regards,

This is an allocation failure for a *huge* allocation (order 5 = 128 KB
chunk) in atomic (non-sleeping) context. I think this may be related to
(1) use of GRO on the receive path to coalesce packets (2) a
netfilter/iptables rule that requires the packet to be duplicated, or
requires the contents to be made contiguous.

Probably because e1000 did not use LRO or GRO there. You can test this
by turning off GRO with 'ethtool -K eth0 gro off'.

However I would also recommend configuring the machine with some swap
space. The kernel has trouble defragmenting memory without swapping.

Once a job is fouled up, anything done to improve it makes it worse.

1. Do you mean gso? I do not see gro as an option on ethtool.

2. I think I know the culprit. I have recently made the machine to
double up as a X-term. Some pixmap updates can easily pass around chunks
that size. I have a couple of other systems with similar hardware so I
will see if I can reproduce it with them.

3. While the machine has a few netfilter rules they are all on another
interface (towards a wifi AP) and it does not do any NAT so no need to
reconstruct packets.

It is my always-on server with everything raid-ed. If I configure swap
the reliability is out of the window. I did that mistake once a while
back (7 years or so) and it ended up with some serious damage. The only
to get swap for it is hardware RAID.

I mean what I said. Install ethtool from squeeze.

That doesn't require contiguous blocks. But it will still reduce the
amount of free memory.

That's strange.

Really, you think Linux hasn't improved in 7 years?

Once a job is fouled up, anything done to improve it makes it worse.

Understood. Will test and submit results.

The only traffic of notice the machine has is NFS, Xterm and a bit of
mysql from time to time. NFS is mostly read and clients use -orsize=4096

Oh it has. It is now much better on handling failed hardware/hardware
gone away. Fair point. I will test how exactly does it look if you swap
to a device and the device suddenly goes away nowdays.

Default Bug#611622: linux-image-2.6.32-bpo.5-686: VM problems

Hi Ben,

You were correct.

It is offload and it is X and/or pulse which is throwing enough TCP at
the system to trigger the memory allocation failures.

You can close the bug now.

Turning off all offloads except checksumming looks like a valid
workaround. I have had the system running for a while. The memory
allocation failures should have shown up by now.

It may be worth it to have an init script as a part of the ethtool
package which sets offloads and defaults to turning off segmentation
offloads at if there is no swap. I will be happy to write it, if you and
the ethtool maintainer think it is a good idea.

Brgds,
