What is the application? How do you know if the application requested more than 2.3GB of locked memory or not? One other thing, the T5540 has the largest memory latency times of all the CMT servers, so you could be seeing some of this.

How much memory does the system have? Is it possible the system is paging? Look at vmstat output.

Hi Steve,

I meant either zone or project .. as i 'm having issue both in zone and project ..

the issue is same .. as per kstat the locked memory is around 2.3G and the value assigned (locked-memory ) is much larger but still application users are complaining they are experiencing a performance issue due to memory .. as they are checking the memory from the RSS column of prstat output for that particular zone/project which is larger than the locked memory as per kstat

See below output for the project
