Description:

Slave processes are having file locks to files in the workspace hanging around after builds are interrupted during copy artifacts step.
I used http://file-leak-detector.kohsuke.org/ to get a stack trace of the lock:

The build log

shows:

Build step 'Copy artifacts from another project' marked build as failure
{code}
I'm guessing there was a network hiccup of some sort
that caused the slave to momentarily lose connection with master during the copy artifacts build step
.
This is easily reproducible by simply aborting the build during
the Copy Artifacts
this
step.
