What does "Warning WorkingSet: Virtual Memory is . . . " log line mean?

The Qlik Sense Engine or QlikView Server service may register the following warnings in the logs:
 

...
Warning  WorkingSet: Virtual Memory is growing beyond parameters ...
Warning  WorkingSet: Virtual Memory is growing CRITICALLY beyond parameters ...
Warning  WorkingSet: Possible cache depletion detected. Depletion factor=1.0 
...

Environment:

 

Resolution:


The host operating system may be running out of sufficient resources for the Engine to perform its tasks. The numbers supplied by the system indicate the current usage of memory by the Engine service against the Low Working Set Limit configured for the Qlik Engine. 

Example after startup:

Information    WorkingSet: Configured Working Set Size is 4.200-5.400 GB (setting 70%-90%)

Where 70% is the (default) Low limit, translating to 4.200 GB.


Warning    WorkingSet: Virtual Memory is growing beyond parameters - 5.205(4.200) GB
Warning    WorkingSet: Virtual Memory is growing CRITICALLY beyond parameters - 5.496(4.200) GB
