Bram Luyten (@mire) commented on DS-1553:
-----------------------------------------
The point is, you shouldn't need 1024MB on small DSpace instance.
What I know for sure:
- the problem manifests in 7.0.29 (verified by myself)
- the problem manifests in 7.0.28 (verified by helix)
- the problem is definitely solved in 7.0.40 (verified by myself + helix)
I remember finding a link on a forum to one of these two issues, relating them
to the source of this problem.
https://issues.apache.org/bugzilla/show_bug.cgi?id=53535
https://issues.apache.org/bugzilla/show_bug.cgi?id=53081
Because I don't know exactly anymore, I'm not 100% positive that it's really
one of these two bugs.
> Huge heap on Tomcat 7.0.29

> When using Tomcat 7.0.29, heap space shoots up to over 600MB when starting up
> DSpace, only deploying the XMLUI exploded war. Even without SOLR.
> Using Tomcat 7.0.40, this is no longer the case and just uses 50MB of heap.
> Right now, I'm not sure whether this is just a local configuration problem,
> or whether there's a serious reason to put a warning in the docs to ensure
> that people don't use 7.0.29.
> Would be great if anybody is able to reproduce/confirm this excessive memory
> usage on tomcat 7.0.29.
> Java opts for 7.0.29 -Xms1024m -Xmx1024m (won't even run without declaring
> more heap space).
