--------------------------------------------
Summary: OOM when using build-report.sh from performance
statistics
Key: IGNITE-21863
URL: https://issues.apache.org/jira/browse/IGNITE-21863
Project: Ignite
Issue Type: Improvement
Affects Versions: 2.16
Reporter: Luchnikov Alexander
The problem is reproduced on a large volume collected using
{code:java}
control.sh --performance-statistics
{code}
statistics, in our cases the total volume was 50GB.
Increasing xmx to 64gb did not solve the problem.
