I am getting the below error message when the SnapSync runs on the dsource database

Failed to format empty blocks of database "DSOURCE_DB" due to: java.lang.AssertionError: sanityCheck failed. Length not multiple of blocksize. Hole info. Datafile: 6_6.dbf (6_6) with blocksize: 131072, hole info: Offset: 1835008, Length: 32210427904.

I am running the version - Delphix Engine 4.2.4.0.

Any thoughts?

Hey Charles, I did a quick look this morning and it appears you are encountering a rare bug. The good news is that we have identified and squashed it in 4.2.4.1, which should be out shortly. If you are a current customer of Delphix, please log a support ticket so that we can add you to the list of people to be notified. I will ask to see if there is a workaround.

Ok. Until 4.2.4.1 is released, the work around is to disable Validated Sync.
