XFS forced shutdown with kernel 2.6.0

[Claas Langbehn]

Hello!


Last night one of my machines running xfs shut down my /homes partition.

That machine was running Azureus (a bittorrent client) with probably
high memory usage.

But even if the memory usage of one program is going near to 100% it
should not force the filesystem to shutdown. Instead it should crash
the application.

I could also think of bad memory, but we did test the SDRAM modules
only a week ago, and they passed memtest86.

After rebooting everything was working fine, again.

So, is this a bug of xfs?


regards,
Claas
