Thanks for the tip. Unfortunately I couldn't get my hands onto the 
system before the message below on the console and SysRq rebooting the 
system today.

From the log the script had stopped to cp -al again and in the same 
tree. My wild guess is that the script shouldn't have had anything to 
talk to network at the time kernel soft lockup nor there isn't any other 
services experiencing network traffic.

I upgraded kernel to 2.6.24.3, ran xfs_repair 2.9.7 on the xfs file 
system and rest the case for next run.

Best regards,
Erkki
