Andrea Schweer commented on DSCR-24:
------------------------------------
I think the real reason is in the XMLUI code, not in Discovery at all. I just
filed a new issue: https://jira.duraspace.org/browse/DS-1070 -- the patch there
should resolve this problem too.
> memory leak in discovery
> ------------------------
>
> Key: DSCR-24
> URL: https://jira.duraspace.org/browse/DSCR-24
> Project: DSpace Discovery Module
> Issue Type: Bug
> Reporter: james bardin
> Priority: Major
>
> I've tracked a significant memory leak in a dspace 1.7.1 installation back to
> the discovery module. The JVM heap would balloon to >1G within a couple days
> depending on usage.
> A heap dump showed discovery objects in all the "leak suspects" reports
> (SimpleSearch, RelatedItems).
> Disabling discovery leveled off the memory use (and as a bonus, brought down
> the latency of the xmlui significantly).
> jdk 1.6.0_24
> Tomcat 7.0.16
> Apache 2.2 proxy using ajp
> I don't have the resources to debug this, but I have a 360MB heap dump I can
> post if someone wants it.
