Repeated XFS Crash on x86_64 fiesty

[Nick Gregory <nick@xxxxxxxxxxxxxxxxxxxx>]

Hi,

I run a number of x86_64 ubuntu feisty (2.6.20-16-server) systems. Each 
has a near identical hardware spec i.e. the systems have a large (>6TB) 
xfs storage partition sat on top of a raid 6 array (using the Areca 
ARC-1160).

Over the last couple of months one system has has its xfs filesystem 
crash on a semi frequent basis (1-2 times a week). Googling around the 
error it first seemed to be memory related so I've done a swap for a 
some new ecc memory - unfortunately the problem persists.

The filesystem is reasonable active but the issue doesn't seem to be 
load related as the issue seems to occur at random times of the day.

Can anyone give me any insight on the best place to start looking to 
track down the issue?

Thanks in advance

Nick
