When destroying a workspace the workspace control logs shows that
workspace/bin/dhcp-config.sh command is failing to backout the dhcp/ebtables
setup for the workspace. However, just prior to these log entries the commands
appear to be successful. My suspicion is that the dhcp-config.sh is being
executed twice in error and failing the second time.

There appears to be no consequences to these error messages.

The specific command called was:

/usr/local/globus-4/bin/workspace -e [SOME EPR] --destroy


The relevant section of the log is:
