What is the cerberus component doing

We noticed that recently in our test cluster all operations take very long to complete. This seems to be due to long lasting “cerberus” tasks being executed with a type “uncharge”. Does anyone know what “cerberus” is doing or how I could speed it up? Whenever we kill the cerberus tasks manually all other queued ‘non cerberus’ tasks start to execute.

Problems connecting PE to PC after upgrade
