  1. Try to apply newer version of Solr, it may handle memory better than older versions.
  2. Try to change GC algorithms (such as CMS, G1..) and monitor it.
  3. Start with flag -XX:+HeapDumpOnOutOfMemoryError. Analyze the heapdump with visualvm, jmap ... to detect any memory leak issues.
  4. Incr -Xmx as much as you can
