A NDMP-based backup problem has been identified in our Data OnTap 5.3.5P2 patch release.
During development of Data OnTap 5.3.6, a deadlock condition was discovered which impacted the NDMP Java implementation. This condition typically manifests itself as an NDMP connection failure during resource depletion conditions. We believe it was first introduced 5.3.5P2. The problem has been resolved in 5.3.5R2P2 and in the forthcoming 5.3.6 release.
If you are running 5.3.5P2, and are experiencing NDMP backup problems similar to the connection failure described above, we recommend that you upgrade to 5.3.5R2P2.
