Packet of death w/NFS+ULOGD+XFS under Kernel 2.6.x?

[Justin Piszcz]

The following e-mail is related to the previous thread:

http://www.uwsg.iu.edu/hypermail/linux/kernel/0506.2/0067.html

Recently, I was copying some images I scanned in (a good 300MB or so) with 
the following command: cp -r images /remote/disk2/share

It caused the _SAME_ lockup as my dd problems.

The weird part is as follows, once the box locks up (the remote host I am 
sending the images to), I reboot and when sets the IP interfaces up, the 
client machine (which the images) is still sending it some kind of 'death' 
packet, as you can see below:

May 14 08:51:27 localhost kernel: ipt_ULOG: error during NLMSG_PUT

I get a few of these messages and then the kernel/console freezes up.  It 
is not until I reboot or shutoff the client machine that the server can 
come up.  I actually thought it might be a ulogd issue, I tried removing 
all of the ulogd rules from my FWALL but still had freezing issues.

Has anyone had similar problems?

^^ Once it gets to this point the console is locked hard, nothing will fix 
except a reboot or shutdown.

^^^ Also, until the other machine is shut off, rebooted or simply 
disconnected from the network, this one will not boot.
