Resolution
The issue can occur if there are deadlock exceptions encountered when selecting the LuDownloadedContentArray object from the db. We can suggest to enable the READ_COMMITTED_SNAPSHOT to avoid the deadlocks for top level objects.
This KB describes the procedure to enable it on the database level :
https://knowledge.broadcom.com/external/article/219553
We would suggest to confirm the configuration first before running the steps in the KB. We can run this statement:
SELECT name, is_read_committed_snapshot_on FROM sys.databases where name like '<sepmdbname>';
If is_read_committed_snapshot_on is set to 0, please follow the KB to enable it.
In addition, please add this parameter in conf.properties file so that the READ_COMMITTED_SNAPSHOT will not be disabled in future upgrades:
scm.upgrade.disable.database.snapshot=false
Restart the SEPM services and monitor. If the issue persist, please collect the Symdiag.
