Lustre Community, We wanted to draw your attention to the changelog for Lustre 1.4.7.3 at: http://www.clusterfs.com/changelog.1.4.7.3.html This release fixes a TCP problem which is rare but can conceivably result in data corruption. We encourage sites running releases older than 1.4.7.3 to consider upgrading. Andy Rudoff Cluster File Systems, Inc.
