We released a patch to the Globus Connect Server Box connector to address a bug that can result in malformed error event messages.
All deployments that run Box have been contacted directly to upgrade their Globus Connect Server deployment to update the globus-gridftp-server-box package to version 0.27.
We recommend all other GCS deployments upgrade at their earliest convenience, in case the Box connector is used in the future.
Please contact sup...@globus.org with any questions or concerns.
