I was not able to reproduce the problem with Lachlan's test program either (although I did not experiment much with the parameters).

Kevin, any idea what kind of io load triggered this problem?

The workload consisted of predominantly (98%) 2-3MB file ingests through an NFS share, with a a few (2%) 1GB file ingests, where the issue seemed to trigger on the larger files.
