Failure to copy artifacts from Master job to slave job

Periodically having builds fail on Copy Artifacts step with following in the log

Unable to access upstream artifacts area. Does source project archive artifacts?
Build step 'Copy artifacts from another project' marked build as failure

There is no other exceptions in the Jenkins log that would indicate what the underlying failure is. The source job of the artifacts executes on the master and the job with the copy step executes on the slave.

I have not seen this problem when both jobs execute on the master.

I am also running in a shared storage configuration where the same mount of the jenkins install is available to both the master and the slaves, but I'm guessing this copy does not leverage this possibility and there is some type of request failure from the slave back to the master requesting the artifacts that must be failing.
