Just to be clear on this... FreeSWITCH pools memory. This is done for
performance reasons, once memory is allocated, its not nessecarily free()¹d
when a call dies. It is normal for the box to increase in memory usage and
then level off at some point... example: its not unusual to see a very busy
box during the daytime using 2G of ram, then at night use that same 2G of
ram since FS will recycle it later. This is actually a good thing since we
arent calling malloc() all the time... You can use the fsctl reclaim_mem
command ona  busy box to get fs to go thru and free() some of that memory
but don¹t expect it to free it all as it will keep some around.

There are also session limits, sps limits, and in sofia limits to concurrent
dialogs, this settings are there you help you control how much traffic the
box will handle and thus either limit the resources it will use or keep it
from melting down on itself

That¹s good to know.  Thank you again for the rapid responses and such.  It
is greatly appreciated.  :)

it may for some time but it will eventually level off

anywhere from 20 to 700 megs is within normal parameters even on an idle
box.

I¹m sure the email app uses way more.  It¹s Outlook after all.  :)

So what you¹re saying is the FS will continue to consume memory for future
use even if nothing is going on?

Thanks for the information and taking the time to address my concerns.

freeswitch uses memory pooling and so do some of it's individual components.
you can expect it to build up to several hundered megs of ram and save it
for reuse.

I bet the email app you are using to write this email is using more ram than
that chart depicts.

I don¹t see any core files.  However, I talked with one of my other guys
this evening and found out he put in a cron job that was supposed to kill FS
and restart it every day at 3am.  I think there was something wrong with how
he did it and FS wasn¹t restarting properly.  I¹ve removed that job and
we¹ll see how long we last.  I¹m still concerned about the ever increasing
memory usage though. I would think that if it doesn¹t level off, eventually
something has to give.

Here¹s what I have for a memory usage graph so far.  As you can see, memory
usage is constantly climbing.  I wouldn¹t think this would be normal.  Since
I updated to 1.0.4pre5, I¹ve made a couple test calls to make sure the IVR
was working correctly.  Other than that, the system hasn¹t been used since
the update about 11 hours ago.

if it already crashed, you would already have core files now you could
trace.
did you witness any crash or find any core files?

mention to the boss if he emails consulting at freeswitch.org he could purchase
a support contract from
FreeSWITCH Solutions and we can make sure his box is stable.

Brian,

Sounds good.  I'll keep an eye on it.

I appreciate the tips.  I'll see about joining the IRC channel.  :)

If you can please refer to the wiki for debugging procedures... I also
recommend you join us on IRC.  We run conference.freeswitch.org
<http://conference.freeswitch.org> with
many participants in a conference all day long without any problems
and we usually keep it up to date every few days when we remember to
do so.  We do not see any memory leaks.

http://wiki.freeswitch.org/wiki/Reporting_Bugs

If freeswitch exits like you say it'll have a core file which you can
run gdb on and it will tell us why it crashed usually.
