Subject [jira] [Commented] (CASSANDRA-4765) StackOverflowError in CompactionExecutor thread
Date Thu, 04 Oct 2012 18:51:47 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13469593#comment-13469593
] 

Jonathan Ellis commented on CASSANDRA-4765:
-------------------------------------------

This is from the SetView returned by Sets.union:

{code}
.     @Override public Iterator<E> iterator() {
        return Iterators.unmodifiableIterator(
            Iterators.concat(set1.iterator(), set2minus1.iterator()));
      }
{code}

I don't think we're taking 100s of unions so increasing Xss is unlikely to help.
