> we make solr run in tomcat. and now there are 10 million records desployed averagely
in solrcloud which has 3 shards. each record's size is about 1.5k. 
> first we used JRE32. then we found it was not fast enough when the current search request
count reached 300. 
> so we think maybe the memory assigned for solr is not enough. and we replace JRE32 with
JRE64, and set "JAVA_OPTS="-Xms2048m -Xmx5120m"" in $TOMCAT_HOME/bin/catalina.sh. but when
we restart the solrcloud, we find it failed. the error log is below:
