We performed a full reindex for the first time against our largest database

reindexing process, both solr nodes shut down with:
java.long.OutOfMemoryError: Java heap space
Running OOM killer script for process blah on port blah
Does this definitely indicate we need more memory or could it just be a heap
space adjustment issue? Is there a way to better diagnose what to do?
https://wiki.apache.org/solr/SolrPerformanceProblems#Java_Heap
There are exactly two ways to deal with OOME: Increase the available
amount of the resource that's running out (heap space in this case), or
change something so the program requires less of that resource.
Depending on the hardware and software configuration, either of these
options might turn out to be impossible.
The rest of that wiki page discusses memory in general as well as heap
memory. If you have questions after reading the page, go ahead and ask
them.
