      It’s been two weeks since the service was bounced, so this is stable usage. I know there are issues with ps; if you have a preferred alternate measurement I can check it.

        I don’t know what specific problem of ps you are referring to, but if you want to check real memory cost of process (USS/PSS) under linux smem might be good tool.
