Jenkins job hangs trying to archive test results?

We are I am trying to leverage a Jenkins pipeline to kick off a set of LoadRunner tests. The archiving step appears to be getting stuck on the zip process. Is this a known issue or is there a workaround? 

FYI the resutls in the workspace are over 3gb. 

This test takes about 12 minutes to run. It's currently over 40 minutes and still stuck on this step. 

console output:
