Hi Henning,
Thanks for the hint.
So, your openser processes should use as private memory:
(8/*udp*/ + 1/*timer*/ + 1/*attendant*/ + 1/*fifo*/) * 1 = 11M
So, overall, all openser processes will use 11 + 128 = 139M plus memory
requested directly from the OS.
looking at your numbers:

it is clearly that you have 8 workers (2 - 9) - the rest of the
processes have a similar VSZ and RSS, so no more mem is required form
the system.
For the workers, I guess there are some script function (from some
modules) that are directly requesting memory (and not via openser mem
manager). Looking at your list:
<quote>
loadmodule "mysql.so"
loadmodule "sl.so"
loadmodule "tm.so"
loadmodule "usrloc.so"
loadmodule "auth.so"
loadmodule "auth_db.so"
loadmodule "maxfwd.so"
loadmodule "mi_fifo.so"
loadmodule "nathelper.so"
loadmodule "perl.so"
loadmodule "registrar.so"
loadmodule "rr.so"
loadmodule "textops.so"
loadmodule "uri.so"

there are none of the modules that use libxml2 or expat, but I see you
are using perl - there were some past problems with mem leaks due this
module, so you may try to take out the module and see if the leak is
still present.

Bogdan

Again, note that openser is not dynamically getting memory from OS at
runtime - all memory that is used by openser is requested from OS at
startup.
Hi Bogdan,
(quoted from a previous mail from him)
Private memory is default. Should I increase
this? Is there a
recommended rule of thumb?
Shared memory is set for 128Mb. There were memory errors at 32Mb but
none since this was increased to 128Mb.
Using the setting 'children = 8'.
Cheers,
Henning
