On Friday May 1st, reloaded mmr00 from mmr01, so they had exactly the same dataset. Since Friday, significant drift has occurred between the two nodes. One example is the following MODRDN request that was made to mmr00. Note: Clocks are tightly in sync between both nodes.

On MMR00, we see the modrdn occur:

Everything looks good on this host. Now on to MMR01... nearly 1.5 HOURS LATER WE SEE:
