On the Store and forward page I get this: Error: Server Error In the log: java.lang.Exception: Unable to add data to memory buffer, buffer full. at com.inductiveautomation.ignition.gateway.history.stores.MemoryStore.insertInBuffer(MemoryStore.java:174) at com.inductiveautomation.ignition.gateway.…

Just edit the DB connection that’s stuck loading, then save changes (even though you didn’t make any). That should restart the connection if there’s some issue.

Seems pretty clear to me. Your quarantine has run out of space. Look at the Store and Forward system’s status page and look at what’s in quarantine.
