So we actually 3 of the 6 machines automatically restart the SOLR service as memory pressure was too high, 2 were by SIGABRT and one was java OOMkiller.
I dropped a pmap on one of the solr services before it died. Basically i need to figure out what the other direct memory references are outside of the heap (marked with the arrows in the image below). anyone have any insight? <http://lucene.472066.n3.nabble.com/file/n4087148/pmap_03.png> -- View this message in context: http://lucene.472066.n3.nabble.com/SOLR-4-2-1-High-Resident-Memory-Usage-tp4086866p4087148.html Sent from the Solr - User mailing list archive at Nabble.com.
