Thanks Santi. I've cc-ed the list as this is probably a common question. The memory allocation can be manipulated in the scripts [1]. On Debian (Ubuntu) machines this manipulates the config in this file: /etc/default/tomcat7 and specifically the line: JAVA_OPTS="-Xmx2g -Xms2g -XX:MaxPermSize=256m -Xss256k" For production systems, if you have the ability to use more than 1 machine, I would recommend setting up SOLR on a separate machine. Theres a playbook for this here [2]. The biocache can point to a different SOLR server by changing the following property in /data/biocache/config/biocache-config.properties # The URL of SOLR services. In the case of embedded SOLR (no for production), this could be a directory path instead solr.home=http://localhost:8080/solr Cheers Dave Martin [1] https://github.com/AtlasOfLivingAustralia/ala-install/blob/master/ansible/ro...

Now I'm having this problem with solr and jvm: ERROR SolrCore org.apache.solr.common.SolrException: Error while processing facet fields: java.lang.OutOfMemoryError: Java heap space I think that I have to config JVM_ARG to assign more memory to the Java heap, but if I'm executing JAVA in a VM with 32 GB and SOLR is consuming more or less 14GB with 10 millions of records. What do you recommend me to assign to Java Heap. Export JVM_ARGS="-Xmx YYYY m -XX:MaxPermSize= ZZZZ m" Thanks in advance, Santi.
