I think this will be fixed by an update to mixlib-shellout. Chef 11 uses flock on a lock file to prevent simultaneous chef runs, but the lock can leak out to processes that chef starts. An upcoming release to mixlib-shellout protects against leaked resources, which should allow chef's locking mechanism to work correctly.

There is a prerelease gem of mixlib shell out 1.2.0 available, you can install it with `gem install mixlib-shellout --pre`. If you're installing chef via omnibus package, `gem` is in /opt/chef/embedded/bin.

Thank you. I'll give that a try.
