Command exited with non-zero status 1
{code}
The command used:
{code}
java -Xmx20G -XX:MaxPermSize=2048M -jar tools/oak-upgrade-1.7.3.jar segment-old:crx-quickstart/repository/ crx-quickstart/repository-oak-upgrade
{code}
Note that when this happened, the logs showed it had copied ~156M nodes in {{/oak:index/uuid/}} (direct children).
I previously tried with only 10G heap, and it failed faster with OOM.
