I am unaware of any UNIX server which correctly reports process memory where the process accesses shared memory using a standard utility like ps. On each UNIX platform there are different utilities that you can use to see real or at least a more accurate measure of process memory usage.

You might try the archives while you want for a more AIX knowledgable poster to reply. I do know that the lsattr command can be used to see some real memory information but the command I have saved appears to be for total system memory and not a specific process.
