Problem
- Confluence may crash eventually due to running out of memory.
- The following appears multiple times in the
atlassian-confluence.log:
ERROR [scheduler_Worker-2] [apache.pdfbox.filter.FlateFilter] decode Stop reading corrupt stream.
Cause
Most probably this PDFBox bug is causing the issue: https://issues.apache.org/jira/browse/PDFBOX-847. The result is in most cases having the Confluence instance running out of memory.
Workaround
- Shut down Confluence
- Remove pdfbox-x.x.x.jar from <CONFLUENCE-INSTALLATION-DIRECTORY>/confluence/WEB-INF/lib
- Download version 1.7.1 from Apache's site: http://pdfbox.apache.org/download.html
- Place the downloaded .jar file to <CONFLUENCE-INSTALLATION-DIRECTORY>/confluence/WEB-INF/lib
- Clear the plugin cache
- Start Confluence
Resolution
Upgrade to Confluence 4.3.7 or later which is now shipped with PDFBox version 1.7.1. Related bug report can be found here: CONFSERVER-27115 - Upgrade PDFBox to 1.7.1
