Re: [zones-discuss] Application leaking on local zone

[AdinaKalin]

This is exactly what I want to understand. No, the application is not 
zones aware. My project is to certify
the application on zones.

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.

I recommend using libumem on the application.

Some folks were nice enough to write about it.

Hello,

I'm struggling with the following problem and I have no idea how to
solve it.
I'm testing an application which is running fine on a global zone,but
memory leaking when installed on a local zone.

The local zone has its whole root and a very simple, basic 
configuration:
bash-3.00# zonecfg -z mdmMDMzone
zonecfg:mdmMDMzone> info
zonename: mdmMDMzone
zonepath: /mdmMDMzone
brand: native
autoboot: true
bootargs:
pool:
limitpriv: 
default,dtrace_proc,dtrace_user,proc_priocntl,proc_lock_memory
scheduling-class: FSS
ip-type: shared
net:
         address: 192.168.109.14
         physical: e1000g0
         defrouter not specified

One of the application processes, when started on global zone, has an
rss of about 5 GB ( prstat -s rss ) and it keeps this size to the 
end of
the test. If I stop the application on global zone and I start it on
local zone, the same process starts with the normal size ( 5gb on 
prstat
-s rss ) but is growing  during the test ( I saw it 25GB on a server
with 32 gb RAM ) until is failing. I don't understand why is this
behavior and if the application has a memory leak, why I don't see 
it on
the
global zone.

Any help is more than welcome!!!
