Filesystem is Advfs on a rack of compaq disks, I assume this is some kind of raid unit, as all disk activity lights typically flash for any file access, and this is supposed to be a high availability system.

This hang was reproducable on this Oracle data file creation, (file is actually created a few seconds before hang, and creating large empty files obviously causes no similar problem), so I am pressed to understand how this can be a hardware issue.
