Summary

Problem

Importing a Word document with embedded images can sometimes result in OutOfMemory errors. Confluence Cloud automatically recovers from this errors but a new import attempt will cause another crash even if memory is added to Confluence.

Diagnosis

Environment

  • Confluence Cloud

Diagnostic Steps

  • Using the "Import Word Document" option, returns System Unavailable caused by Confluence running out of memory.

Cause

CONFSERVER-21717 - Word documents with embedded images can sometimes result in OOM errors

Solution

Workaround

Use Confluence Pandoc Connect free add-on.

It extends the import functionality and addresses memory handling problems that adds stability to Confluence Cloud imports.

To install, follow the Installation notes in the Marketplace.

Please note that although the add-on is Unsupported by Atlassian we recommend it's usage while the Confluence bug is being addressed.
