Hey Denis, * How big is your index in terms of number of documents and index size? * Is it production system where you have many search requests? * Is there any pattern for OOM errors? I.e. right after you start your Solr app, after some search activity or specific Solr queries, etc? * What are 1) cache settings 2) facets and sort-by fields 3) commit frequency and warmup queries? etc
Generally you might want to connect to your jvm using jconsole tool and monitor your heap usage (and other JVM/Solr numbers) * http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html * http://wiki.apache.org/solr/SolrJmx#Remote_Connection_to_Solr_JMX HTH, Alexey 2011/6/1 Denis Kuzmenok <forward...@ukr.net>: > There were no parameters at all, and java hitted "out of memory" > almost every day, then i tried to add parameters but nothing changed. > Xms/Xmx - did not solve the problem too.
