Problem

When saving a page in Confluence the editor throws the error

Unable to communicate with server. Saving is not possible at the moment

The following appears in the atlassian-confluence.log

org.springframework.dao.TransientDataAccessResourceException: Hibernate operation: could not execute statement; SQL []; Could not allocate space for object 'db_owner.BANDANA'.'PK__BANDANA__DCCFB4095D97CB68' in database 'confluenceDb' because the 'PRIMARY' filegroup is full

Diagnosis

Environment

• Confluence is using MS SQL database

Cause

This is caused by filegroup issue which is specific to SQL server

Workaround

• Check if the hard drive of the database server still have plenty of space available

• Delete unnecessary object from your file group

  • Increase the fixed size of your primary filegroup.

• Check your SQL Server version. SQL Server Express version 2008 and earlier had the limitation of 4GB maximum Database size. SQL Server Express 2008 R2 and onwards have limitation 10GB maximum database size.
