Re: [zones-discuss] Application leaking on local zone
I noticed that you configured your zone with proc_lock_memory, so that could explain the large RSS, but that would be same for the global zone too. Before you start with libumem debugging, I would try ppriv(1) command with the -D option to see if your app is silently failing because of a privilege issue. Do you have a pmap(1) of the offending process? BTW, what does your application do in that you have to make it zone aware? AdinaKalin wrote: This is exactly what I want to understand.

Re: [zones-discuss] Application leaking on local zone
If you can provide some ::findleak details about the particular memory leak, perhaps someone can help.

Re: [zones-discuss] Application leaking on local zone
As Steve said, libumem will be your best tool for this job. Is the program zone-aware? The program might behave differently (i.e., its logic is different) while running in non-global zones and the alternative code paths might be leaking memory.
