Console log is telling me that database is locked for many apps. How do I unlock?

I'm trying to diagnose a MacMini that is painfully slow to start up. I already check the filesystem (fsck) and the disk (Disk Warrior). I am running High Sierra. My Mac is fine once it's up and running but something has to be going wrong during boot up. Looking at the console log, I'm seeing a ton of "database is locked" messages for numerous apps including CalendarAgent, AddressBookSourceSync, soaagent, routined and so forth. Where are these databases and how can I unlock them? The items I've found online regarding sqlite databases have been for Windows and Linux, not finding anything anywhere on this specific issue. How may I analyse this problem and unlock these databases?
