Post-Upgrade Recovery File Generation Results in OOM If Size of BodyContent Is Really Large

    Details

      Description

      We have seen an issue where an instance would run into OOM, despite having a really large Heap (10GB), because the size of their BODYCONTENT is really large. We should not load the entire BODYCONTENT into memory to generate this recovery file.

      See:

      Workaround

      Disable the upgrade recovery file generation by adding this to your startup parameter:

      -Dconfluence.upgrade.recovery.file.enabled=false
