I'm trying to stress-test solr (nightly build of 2009-10-12) using JMeter. I set up JMeter to post pod_other.xml, then hd.xml, then commit.xml that only has a line "<comit/>", 100 times. Solr instance runs on a multi-core system.
Solr didn't complian when the number of test threads is 1, 2, 3 or 4. But when I increased the thnumber of test threads to 8, I saw this error on the console: SEVERE: org.apache.solr.common.SolrException: Error opening new searcher. exceeded limit of maxWarmingSearchers=2, try again later. What does this mean? Why Solr tries to make warm up searchers when I'm posting documents, not searching? Do I need to set this maxWarmingSearchers to greater than the number of CPU cores? Thanks. T.
