Symptoms

After upgrading Confluence, Team Calendars for Confluence needs to be updated from version 4.x.x to version 5.x.x. However, the update process takes very long time and never finish.

The following appears in the atlassian-confluence.log:

2015-01-15 05:30:28,454 WARN [UpmAsynchronousTaskManager:thread-3] [confluence.util.profiling.DurationThresholdWarningTimingHelperFactory] logMessage Execution time for publishing event com.atlassian.confluence.event.events.plugin.PluginInstallEvent(com.atlassian.confluence.extra.team-calendars) took 47192339 ms (warning threshold is 5000 ms)

Diagnosis

• Ensure that the database is configured according to Database Configuration documentation

• Enable Team Calendars for Confluence debugging (log4j.logger.com.atlassian.confluence.extra.calendar3.upgrade.task=DEBUG) and the following entries are shown:

  2015-01-26 12:34:54,063 INFO [active-objects-init-system tenant-0] [calendar3.upgrade.task.CalendarContentTypeReindexingUpgradeTask] upgrade ====================End Upgrade Task for reindexing Custom Content Type Team Calendars for Confluence==============================

  ... however it still ends up with the WARN message shown in the Symptoms section.

Cause

The exact cause hasn't been found yet. This could be caused by incompatibility between older UPM and Team Calendars for Confluence 5.x.x.

Resolution

1. Right after Confluence upgrade process, update UPM to the latest version
2. Update Team Calendars for Confluence
