Hi, this is the GC data map record by Jconsole come with JDK1.5. One houre later, major GC become so busy...and the Throughput in Jmeter become decrease with the time. I have increase the heap size above to 1300M. If more rhan 1300M, there will throw error ...So maybe in my enviroment the heap size limited to about 1.3G.

Should i increase the survior space?
