Subject [jira] [Commented] (OAK-2557) VersionGC uses way too much memory if there is a large pile of garbage
Date Mon, 09 Mar 2015 10:04:38 GMT

    [ https://issues.apache.org/jira/browse/OAK-2557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14352736#comment-14352736

Stefan Egli commented on OAK-2557:
----------------------------------

Could it be a side-effect of too many nodes being indexed due to OAK-2559 ?

> It has been noticed that on a system where revision-gc (VersionGarbageCollector of mongomk)
did not run for a few days (due to not interfering with some tests/large bulk operations)
that there was such a large pile of garbage accumulating, that the following code
> {code}
> VersionGarbageCollector.collectDeletedDocuments
> {code}
> in the for loop, creates such a large list of NodeDocuments to delete (docIdsToDelete)
that it uses up too much memory, causing the JVM's GC to constantly spin in Full-GCs.
