Java heap space issue on Solr4

Jump to solution

Hi,

I have a Solr issue during alfresco startup (Alfresco CE 5.2; Solr4).

Following configurations in solrconfig.xml for both workspace and archive Spaces Store has been changed to:

mergeFactor change to 25
ramBufferSizeMB change to 64

as explained here Alfresco Tuning Shortlist – : : blyx.com : : Blog : : Toni de la Fuente : : 

and other sources suggested.

Xmx setting is set to 12GB ([ALFRESCO_DIR]/tomcat/bin/setenv.sh)

JAVA_OPTS="-Xms512M -Xmx12G $JAVA_OPTS " # java-memory-settings

Following are logs from Tomcat's catalina.out which shown heap space issue. What file and configurations should I take care?

Thanks,

Re: Java heap space issue on Solr4

Jump to solution

The problem has been solved since default Alfresco 5.2 heap space setting is only 1 GB which configured in /opt/alfresco-community/tomcat/scripts/ctl.sh. I increase Xmx setting to 12 GB which has same value configured in /opt/alfresco-community/tomcat/bin/setenv.sh (by Alfresco installation).

I also post this  - which lead solving this issue :-)

When does this exception happen? Every time you upload a document? Or when you upload some specific one?

Re: Java heap space issue on Solr4

Jump to solution

how much memory do have? Did your Index start up without the change of the mergeFactor?

I had to increase memory to 32GB for a big repository (about 15 mio nodes). Physical memory of the machine is about 64GB and Solr needs it all for heap and so on.

If you want to dump the heap in this moment, there was a hint on apache solrs docs-site:

If you want to see the heap when OOM occurs set "-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/path/to/the/dump" (courtesy of Bill Au)

Hi:

You may calculate the JVM memory needed for your SOLR node:

It happens only during alfresco start for about an hour. During that time I can't login.

When this Solr issues stopped, I can login and system run normal (load speed), but I can check that the indexing process not complete properly. I do the full reindex (deleting index of archive and workspace; model and contents) before start alfresco.

I have 24 GB installed on my CentOS 6.6 (IBM X3300).

And now I restart with default of mergeFactor and ramBufferSizeMB, but it still slow start up.

I will try your suggestion.

Thanks, Cesar..

It seems getting my docs bigger, I should pay high attentions to Solr :-|

Re: Java heap space issue on Solr4

you can also look at your cpu utilization on solr startup with top (press 1 to see all cpus). If you experience that only one cpu is used up to 100%, then it's most likely that you have a lot of "litter" in your DB. Solr detects "litter-nodes" and checks if they are referenced by any other node. This seems to be single threaded.

It seem all CPU are used by process.
