I started running the test on 2 other machines with similar specs but more
RAM (4G). One of them now has about 60k docs and still running fine. On the
other machine, solr died at about 43k docs. A short while before solr died,
I saw that there were 5 searchers at the same time. Do any of you know why
would solr create 5 searchers, and if that could cause solr to die? Is there
any way to prevent this? Also is there a way to totally disable the searcher
and whether that is a way to optimize the solr master?

I copied the following from the SOLR Statistics page in case it has
interested info:
