Description
In rare cases, heavy workloads can lead to system deadlocks. This has rarely been observed on systems with many client connections and/or out-of-memory scenarios. In this case, some internal communication messages could not be processed, resulting in partial or complete system deadlocks.
Workaround
Restart the database.
Fix
The deadlock problem has been fixed and there is no negative impact on the usability of the database.
