Heap space problems affect the entire process, and the reason for needing more heap may not be apparent from logs. An OutOfMemoryError may be thrown from *ANY* part of the program when you run out of heap, even pieces of the program that aren't the actual problem. https://wiki.apache.org/solr/SolrPerformanceProblems#Java_Heap Thanks, Shawn
