I'm seeing the following exception in traces: "Could not allocate space for object 'dbo.plan_persist_runtime_stats'.'plan_persist_runtime_stats_cidx' in database 'DBName' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.".
What/where is this? I don't find it in system tables in the specified database or master. It sounds like an internal table.
How can I correct the problem?
Microsoft SQL Server 2017 (RTM-CU5) (KB4092643) - 14.0.3023.8 (X64)
There is plenty of space on all drives. The specified database does not limit growth.
Thank you.
