      When attempting an upgrade to 5.5 the logs will show the following:

      The catalina logs from this time show:

      SEVERE: A child container failed during start

      	at com.atlassian.confluence.upgrade.AbstractUpgradeManager.upgrade(AbstractUpgradeManager.java:134)

      The pre-upgrade recovery file should be writing straight to disk, so shouldn't be susceptible of OOMEs at all.

      Steps to Replicate:

      1. Install Confluence 5.4.4 (or any version prior to 5.5)
      2. Install a number of add-ons, particularly large add-ons such a Gliffy
      3. Attempt the upgrade

      Workaround:

      Please refer to Upgrade to 5.5 hangs when generating pre-upgrade recovery file.
