This morning our instance default version on land had a date of November 13, 2013 after a compress to state 0 last night by IBM. There is no custom code running in the compress, it is done using core functionality through ArcCatalog. However all of our updates since then are in place (meaning the database does not really reflect its state from November 2013).
If anybody could give us a lead to pursue it would be very much appreciated. Thanks.
