Symptoms

The work list page keeps loading and no results found. A quotaexceedederror is thrown in the network trace.
 

Diagnoses

The error causes an infinite spinner because execution has stopped the spinner overlay will not be removed and rendering of worklist rows is not handled from that point on. This is a known issue whereby the worklist control is unable to load more than 100 workflow instances.
 

Resolution

This is slated to be included in the 4.6.11 release. As a workaround, you may do the following:
1. Clear localstorage - go to the console tab in the f12 tools and run localStorage.clear() and sessionStorage.clear()
2. Use the filter feature to limit the payload
