Ralph Goers reassigned COCOON-1574: ----------------------------------- Assignee: (was: Ralph Goers) > Memory Leak with XMLFileModule > ------------------------------ > > Key: COCOON-1574 > URL: https://issues.apache.org/jira/browse/COCOON-1574 > Project: Cocoon > Issue Type: Bug > Components: * Cocoon Core > Affects Versions: 2.2 > Environment: Operating System: Windows XP > Platform: PC > Reporter: Ronald Blaschke > Fix For: 2.1.11 > > > I'm currently looking into a memory leak issue at Apache Forrest. Forrest's > site currently needs to be built with -Xmx128m because of this. I believe the > issue is originated at Cocoon's LinkRewriterTransformer or XMLFileModule. > A memory profiler shows lots (30MB+) of DOM DocumentImpls (150+ objects), > which > get referenced by XMLFileModule.DocumentHelper. Their URIs are linkmap-xxx. > LinkRewriterTransformer#createTransformedLink(String) uses a > InputModuleHelper, > which seems to reference a XMLFileModule. > ... > newLink = (String) modHelper.getAttribute(this.objectModel, > ^^^^^^^^^ > ... > The XMLFileModule keeps the visited documents in a map, which is where they > build up. > Just for testing, I changed XMLFileModule#getDocumentHelper(Configuration) > from > this.documents.put(src, new DocumentHelper(reload, cache, src, this)); > to > return new DocumentHelper(reload, cache, src, this); > Thus, a new DocumentHelper is created every time, instead of caching them. > The > result: No more memory problems, Apache Forrest's site builds again with > -Xmx32. > Ron -- This message was sent by Atlassian JIRA (v6.2#6252)
