QueueMetrics:
You can see it from the DBTEST page of QM, select "View configuration" then "Current memory properties".

emilec:
Looks to me like you have 32-bit java. Here is what I have on my 64 bit system

# /usr/local/queuemetrics/java/bin/java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)

What is the output of:
# uname -a

coolname:
yes 32bit
after search the google，i found itmay because of the limit of jvm , after a test of "java -XmxXXXXM -version",i found a max stable number is 2600

coolname:
a test in centos 6.2 64bit, 7000M memory is ok

now report
