             Summary: Reduce CI heap space by 25%
                 Key: FLINK-28004
                 URL: https://issues.apache.org/jira/browse/FLINK-28004
             Project: Flink
          Issue Type: Technical Debt
          Components: Build System / CI
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.16.0


I've recently seen several builds where docker crashes again with out of memory 
errors.

Our current memory configuration is a bit optimistic and relies on all forks 
_not_ hitting the upper limit.

If we'd reduce the heap space by 25% everything could run at maximum without 
memory running out.
