Urgent Anchor Service Advisory

Partners with Anchor agents between versions through are strongly advised to upgrade to the latest version to avoid slow performance, unexpected sync collisions, or improper sync behavior under certain conditions.


Only agents on versions through are affected. Agents on versions prior to 2.5.0 are not affected.


  • Affected agents can cause unexpected collisions, stop syncing, or sync improper versions under certain rare race conditions.
  • Affected agents can, in certain cases, mishandle agent re-registration.
  • Affected agents that are in a resyncing state rebuild their local sync state database; in these builds, this operation is very slow if you have hundreds of thousands of files or dozens of roots on a machine.

Please refer to the Anchor version release notes for additional information.


Anchor version 2.5.0 introduced a substantially enhanced sync engine that delivers near-instant sync of metadata (file/folder renames, deletes, etc.), and dramatically faster sync performance by concurrently synchronizing many files at the same time. The sync engine also has separate sync queues for small files and large files, ensuring that small files are always up to date, even when very large files are synchronizing. In some cases, this increased level of parallelism in the sync operations caused conditions that led to the symptoms described above.


Anchor version was released on Friday May 13, 2016 and fixes these issues. Please follow these steps:

  1. If you are a SaaS Anchor user, agents will automatically update to version in most instances. If you are a private cloud Anchor user, first update your private Anchor server(s) to the new version. Agents will then begin to automatically upgrade to the new build.
  2. Reference the Checking the Anchor Agent Version Knowledgebase article to help you quickly find and update out-of-date agents.
  3. If necessary, help end users resolve collisions by referencing the Manually Resolving a File Sync Conflict Knowledgebase article.

If you continue to experience issues or have trouble upgrading agents, please contact eFolder Support (

We are excited to announce that the Anchor Knowledge Base will soon merge with Folder’s Knowledge Base community. Anchor has been a part of the eFolder family of products since September of 2013, so we are looking forward to this move to best serve our partners. 

Please note that the Anchor Community, including our Feature Request service, will remain open and active until further notice.

What does this mean for me?

  • For the time being, you can find Anchor Knowledge Base articles in the Anchor Community and the eFolder Knowledge Base
  • Soon, the Anchor Knowledge Base will be officially decommissioned; however, you will still have the ability to view redirect links.
  • The Anchor Community, including our Feature Request service, will remain open and active until further notice.

Where can I find Anchor-related information in eFolder's Knowledge Base community?

Redirect links have been added within each existing Anchor Knowledge Base article, linking you to the appropriate article in the eFolder Knowledge Base.
