Hi ,
As suggested i looked at heap dumps, for any trace of memory leaks. But i
couldn't trace any.
I ran the same test on Ubuntu10.04, Ubuntu 9.10 and CentOS to confirm that this
memory leak was not at the OS level. But the results are same in all 3 cases.
Memory usage by all the service instances and client request processes becomes
constant once the processing starts. But broker memory usage keeps on
increasing.
My server has 16Gb ram and 8 cores.
I provided heap size to both client and broker ( 1Gb to 2Gb).
Here are top command output of client,service and broker
