[ http://issues.apache.org/jira/browse/AXIS-2278?page=all ]
Kevan Miller updated AXIS-2278: ------------------------------- Attachment: enumMapPatch.txt Here you go... I checked out from current trunk. Built from the source and then run under Geronimo. With the change, I don't see enumMap holding onto Geronimo classloaders... FYI, there's another potential leak around o.a.a.description.TypeDesc.classMap/classMaps (1.3 is different than trunk? Not sure why...). Either way, it's part of a chain of references that is keeping ClassLoaders alive. I need to investigate some more... May be a Geronimo problem. Will raise an issue, if I confirm there is a problem. > Memory leak cause by JavaUtils.enumMap > -------------------------------------- > > Key: AXIS-2278 > URL: http://issues.apache.org/jira/browse/AXIS-2278 > Project: Apache Axis > Type: Bug > Versions: 1.3 > Environment: Sun JDK 1.4.2/WinXP > Reporter: Kevan Miller > Attachments: enumMapPatch.txt > > I'm chasing down some Geronimo memory leaks when deploying/undeploying the > DayTrader sample application. > One memory leak I see is caused by o.a.a.utils.JavaUtils.enumMap. JavaUtils > is loaded by a parent ClassLoader but is has strong references to classes > (the keys of enumMap) which were loaded by child ClassLoaders. This prevents > the ClassLoader, and the classes it has loaded, from being GC'ed. This means > we'll eventually run out of PermGen memory... > I converted enumMap to be a WeakHashMap and I now see the ClassLoaders being > GC'ed. I didn't download using cvs. So, I don't have a patch. I'm happy to > generate one, if you'd like... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
