> There have been some excellent logging fixes in 6.3 (http://www.cominvent.com/2016/11/07/solr-logging-just-got-better/).  However now, by default, Solr is logging a great deal of garbage collection information.
> It seems that this logging is excessive, can we make the default logging to not be verbose?
> For linux/mac setting GC_LOG_OPTS="" in solr.in.sh seems to work around the issue, but looking at solr.cmd I don't think that will work for windows.
