-------------------------------------------

             Summary: Roll over GC logs by default via bin/solr scripts
                 Key: SOLR-7506
                 URL: https://issues.apache.org/jira/browse/SOLR-7506
             Project: Solr
          Issue Type: Improvement
          Components: scripts and tools
            Reporter: Shalin Shekhar Mangar
            Priority: Minor
             Fix For: Trunk, 5.2


The Oracle JDK supports rolling over GC logs. I propose to add the following to 
the solr.in.{sh,cmd} scripts to enable it by default:
{code}
-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=20M
{code}

Unfortunately, the JDK doesn't have any option to append to existing log 
instead of overwriting so the latest log is overwritten. Maybe we can have the 
bin/solr script roll that after the process is killed?
