G'day! Did you turn off and remove the Active Anti Entropy files before upgrading? >From the 1.4.8 release notes: IMPORTANT We recommend removing current AAE trees before upgrading. That is, all files under the anti_entropy sub-directory. This will avoid potentially large amounts of repair activity once correct hashes start being added. The data in the current trees can only be fixed by a full rebuild, so this repair activity is wasteful. Trees will start to build once AAE is re-enabled. To minimize the impact of this, we recommend upgrading during a period of low activity.
