After the updates last week (starting Wednesday 2024-01-31) many applications have hit what seem to be an internal bug in the lustre file-system client.

Typically this manifests itself through jobs not terminating/finishing properly. Nodes get stuck 'completing' after job finish for longer periods of time. Other jobs fail to start up properly on all nodes.

Several applications seem to be hit by the bug. However, 'vasp' applications seem more unfortunate.

Work to apply a work-around is on-going.
