Keeps getting stuck on Optimizing Guide Data

For about the last week my Tablo gets stuck on the spinning “Optimizing Guide Data” message when I log in. If I power cycle the Tablo it will work normally for a while and I was able to verify my guide was up to date and update to the latest firmware. Any ideas what is going on? I have a 4 tuner model

Maybe database corruption? Have you logged a support case yet?
