Burp Suite 2.0 doesn't play well with Google Drive File Stream

Mikail | Last updated: May 16, 2019 10:22PM UTC

I've had issues with Burp and GDrive File Stream on Windows 10 (fresh install). Specifically, automatic backups fail and the explicit saving of a project in the GDrive location (G:/ by default) results in the following error message: "Failed to create new project file: java.nio.channels.OverlappingFileLockException" The problem persists even after marking the destination directory as 'Available Offline' in GDrive. Unfortunately, this has resulted in me losing hours worth of data as I was under the impression that my data was being autosaved.

Mikail, the error message you are encountering occurs when two instances of Burp try to access the same project file. Are you running two instances of Burp? Have you used Google Drive File Stream with Burp Suite projects successfully?

We have the same issue with Google Drive File Stream. Any way around it?

And then, when I close and reopen the project, the project file is corrupted..

Hi, Burp uses memory mapped files to load projects, which causes issues on shared drives. We always recommend using a local hard drive for Burp Project files.

Hi Ben, First of all, in that case, Burp should not allow me to close the project without any warnings, loosing all the work done before that. Is there a view on when this will be fixed?

Hi, Firstly, apologies for the loss of your work. Secondly, we think that your suggestion is a great idea. I have added a feature request into our development backlog so that users are warned about their use of shared drives in order to prevent data loss. We cannot currently provide an ETA of when this will be implemented but I have added this ticket against the request and we will update this forum post when we have some more news to share. Please let us know if you require any further information.
