Grégory Joseph commented on MAGNOLIA-1998:
------------------------------------------
Sean : I edited the status to reflect your comment; it's still unclear as to
why only upgrading Jackrabbit would make the issue worse, though.
Qu : the purpose of this last test was to see how the GC behaved with less
memory, i.e. trying and detect a potential leak. Resetting your Xmx to a more
viable limit will produce less scary graphs ;)
Another question now: could you provide some details as to how this was tested?
Is this real or generated traffic? Author or public instance? It seems to match
our internal tests on a public instance, browsing with the anonymous user, so
that's a rather good sign on that side of things.

> Several users have reported memory issues. We're creating this issue to
> collect information, reports and other evidence. Please attach relevant files
> and leave comments on your experiences. Thanks!
> *Current status:*
> * We're investigating about this issue, but we're lacking evidence of a real
> leak in Magnolia 3.5 when used with an external database at the moment. (see
> comments below)
> * There have been too many architectural changes in 3.5 to backport the fixes
> to the 3.0 branch
> * The following definitely helps:
> ** Using an external database such as MySQL
> ** Using *Magnolia 3.5.x* (and Jackrabbit 1.3.x)
> * If you're experiencing OutOfMemoryError: PermGen space, you need to
> increase the -XX:MaxPermSize JVM setting.
> * If you're still having memory issues after applying the above advices,
> please report them here with the following information:
> ** Operating system:
> ** Java version:
> ** Container (tomcat, jetty, ...) and version:
> ** Precise JVM settings (JAVA_OPTS, CATALINA_OPTS, ...)
> ** How is your container started:
> ** Is there any specific operation that triggers your memory issues?
> ** Any stacktraces or relevant log files (in attachment, with your name
> in the filename, please)
