Thanks for your quick reply. We will increase the heap size.
The question just is if there is a known issue causing more memory to be
used?
Because it was fine before the upgrade.
Best Regards

Hi guys,
We are running a DSpace 5.1 instance with about 25000 items on Ubuntu
Server 14.04 with OpenJDK 1.7.0_75. We set Xmx to 2g so the JVM has 2
Gigabyte of RAM.
If I inspect the memory usage I see that there are about 1900 MiB in
use. So most of the memory is used.
This leads to OutOfMemoryErrors during nightly cron jobs like
optimizing
Solr and sometimes during the day.
Has anyone seen a similar behaviour and solved the problem?
Additional facts:
- Was working fine on 4.1
- After tomcat restart about 500 MiB memory of the JVM used
- 5 Minutes later 1074 MiB used
- 10 Minutes later 1702 Mib used
- About 14000 publication with full text (indexed every night with the
PDF Extractor)
- About 11000 publications without full text
- xmlui, oai and solr activated
- Ubuntu Server 14.04.2
- Tomcat 7.0.52.0
- OpenJDK headless 1.7.0_75
- Solr: authority core=empty, oai core=114,47 MB, search core=3.57 GB,
statistics core=387.82
- JVM 2GB
- System 4GB
Any ideas? Help would be very appreciated
