Hi all,
assigning more memory (2GB) to Tomcat has not solved our problem. Once the
cronjobs for the filtermedia and stats have started, all RSS requests again
result in
java.lang.NullPointerException

The server has 6GB RAM. We have assigned 2GB to Tomcat and 512M to other java
processes. Running DSpace 1.5.2, on SLES11, Tomcat6 and SUN Java 1.5.
Any ideas on how to solve this?
Best regards,
Francis Brouns

Hi Bram,
it seems related to our memory problems. Restarting Tomcat solved the problem
and RSS are shown as they should. We have increased memory allocation to Tomcat
from 1GB to 2GB, in the hope we can prevent running out of memory.
It remains strange though, because the site would display normally. Only the
RSS feeds were giving errors.
Regards,
Francis Brouns

Hi Francis,
does the problem go away when you change:
#harvest.includerestricted.oai = false
into
harvest.includerestricted.oai = true ?
I'm not sure, but the ListIdentifiers call might also be used for the RSS, so
it's related to http://jira.dspace.org/jira/browse/DS-212
In any case, that specific error is fixed in DSpace 1.6 with the attached patch.
regards,
Bram Luyten

Hi,
Last week we upgraded our DSpace 1.4.2 server to DSpace 1.5.2. The tests at the
testserver went all fine. Now on the production server we are running into
problems we did not encounter at the testserver. For example with the RSS feeds.
The configuration in dspace.cfg is:
harvest.includerestricted.rss = false
#harvest.includerestricted.oai = false
harvest.includerestricted.subscription = false
On the test server this is working fine. On the new production server, we get
internal server errors on the RSS feeds. An example error message is given
below.
On the mailing list there are comparable messages, but they refer to the
OAI-PMH harvest. In our case, the harvest is not causing any problems.
Any tips on how to trace the source of this problem are welcome.
