For normal execution nodes, we set a complex_value h_vmem; but the webgrid nodes have none. So I assume the grid just distributes the web services by load. I'll calculate the current (theoretical) virtual memory con- sumption of the webgrid nodes based on the jobs running on them and then set a value ad interim that makes sense to me (cf. also https://phabricator.wikimedia.org/T107665 ("Deter- mine and deploy proper h_vmem resources for execution nodes")).
