Hi; Jack has an answer for a PermGen usages:
"PermGen memory has to do with number of classes loaded, rather than documents. Here are a couple of pages that help explain Java PermGen issues. The bottom line is that you can increase the PermGen space, or enable unloading of classes, or at least trace class loading to see why the problem occurs. http://stackoverflow.com/questions/88235/how-to-deal-with-java-lang-outofmemoryerror- permgen-space-error http://www.brokenbuild.com/blog/2006/08/04/java-jvm-gc-permgen -and-memory-options/ " You can see the conversation from here: http://search-lucene.com/m/iMaR11lgj3Q1/permgen&subj=PermGen+OOM+Error Thanks; Furkan KAMACI 2014-02-28 21:37 GMT+02:00 KNitin <nitin.t...@gmail.com>: > Hi > > I am seeing the Perm Gen usage increase as i keep adding more collections. > What kind of strings get interned in solr?
