Description

nimbus jobs are causing a Gig E switch to hang. Disabling nimbus partition until I can get the Nimbus VM traffic off of the uplink.

Resolution

Initially we retired an older switch that was throwing errors. We also had an issue with nimbus VM's not shutting down correctly. The worksp were being re-used, so duplicate mac addresses were being used on the new switch. Nimbus partition was put back in production last night.
