Do you happen to have any snapshots on any of the filesystems to which you might be writing at the time of the panic? I don't know how I determined it, but I found that the panic was the result of a snapshot on my /var filesystem. Removing the snapshot solved the panic. -- Jonathan Fosburgh AIX/SAN Administrator UT MD Anderson Cancer Center Houston, TX Home Page: http://www.fosburgh.org
