The following appears in the atlassian-confluence.log:

Clearing pending acquires. While trying to acquire a needed new resource, we failed to succeed more than the maximum number of allowed acquisition attempts (30). Last acquisition attempt exception:

WARN [main] [sf.hibernate.cfg.SettingsFactory] buildSettings Could not obtain connection metadata
java.sql.SQLException: Connections could not be acquired from the underlying database! 

Caused by: com.mchange.v2.resourcepool.CannotAcquireResourceException: A ResourcePool could not acquire a resource from its primary factory or source.


Specific environments affected:

  • MySQL 5.1 


Installed on certain linux distributions will not, by default, install the innodb storage engine.


  • Upgrade to MySQL 5.5 as the storage engine is enabled by default for the affected linux distribution
