Summary: pkg memory management

Initial Comment:
performing contact dumps from in memory with such commands as:

# openserctl ul show
or
# openserctl online

produces error:

> Aug 11 17:25:06 test /usr/sbin/openser[15267]: DBG:mi_fifo:mi_parse_node:
end of input tree
> Aug 11 17:25:06 test /usr/sbin/openser[15267]:
DBG:mi_fifo:mi_fifo_server: done parsing the mi tree
> Aug 11 17:25:06 test /usr/sbin/openser[15267]: ERROR:core:add_mi_attr: no
more pkg mem (24)
> Aug 11 17:25:06 test /usr/sbin/openser[15267]:
ERROR:mi_fifo:mi_fifo_server: command (ul_dump) processing failed

this comes out after 20 days of openser-1.3.2 operation with couple of
thausands of contacts.

Hi henningw,

still monitoring situation. I was still not able to recompile with that
flag, because of production system uptime requiremts, but im still planning
to do that. I'll post results as soon as i will be able to determine
outcome.

Hi Antanas,

any updates for this bug, does the recompile with the QM_JOIN_FREE helped
you?

BTW, If you're really adventurous (and have a good QA process) then you
could also try to recompile without PKG_MALLOC defined. The server will
then be use the system malloc instead of the fixed size pool (you need to
use a recent branch for this, i did a fix for this case). Performance will
probably be somewhat worse, but you if you then still problems with
fragmentation, you need to blame the linux kernel/ glibc. :-)

Try compile with -DQM_JOIN_FREE and see if you run in same situation. You
can add that define in Makefile.defs, there is a section where the defines
are listed.

hello miconda,

i've been running "openserctl online | wc" pretty frequently. Lets say
from 50 to 100 times in that pediod.

Hi,

if i remember correctly, Dan also reported this problem some times ago on
the devel list. Perhaps we really should investigate to get rid of this
pkg_mem pool, and replace it with plain malloc.. 

In the meantime its probably possible to work around/ delay this problem
by increasing the pkg memory pool size, or i'm wrong?

this might be memory fragmentation. How many times you run openserctl ul
show in this period?
