That assumption is based on common memory allocation patterns. Biggest
ones typically come from tm, around 20k / transaction.
I also assumed you set the /fr_timer/ to a lower value (say 10 seconds).
So, in order to consume ~150MB of memory (tm's ratio out of 220MB),
OpenSIPS needs to be holding only 7500 transactions, thus 750
transactions / sec given my timer assumptions, or 250 transactions / sec
by default.
I went with these assumptions as soon as I saw that /used_size/
eventually returned to normal: 3MB, so it's doesn't look like we're
dealing with a leak.
So either bad performance tunings or some DOS attempts.

Hello Liviu ,
This opensips is on a small carrier, we expected in some weeks reach
almost 2000 simultaneos calls, 750 is something that can happen right
now, we have all kind of customers like call centers, small companies
, residencial customers and other carriers, so we realy want to reach
a high number of calls with opensips, but 750 cps is diferent than
simultaneos calls (i think), i will check if we are getting some kind
of DOS attack
i will change the memory parameters as you suggest.
Just one question for you, how you interpret the value below as 750 cps ?
shmem:used_size = 3401120
shmem:max_used_size = 226816344

Hello Mike,
MySQL data looks like peanuts. We can safely ignore it. The
following stats are quite interesting:
shmem:used_size = 3401120
shmem:max_used_size = 226816344
From the *tm* module's point of view, this means that your server
was hit, at some point in time, by a traffic of over 750
transactions/sec! If we add the memory consumption of other
modules (dialog, usrloc), and a more aggressive peak hour, it may
be quite normal for memory consumption to reach 1GB!
Can you share some details about the nature of your traffic? Do
you expect traffic of over 750 cps regularly? If yes, then:
* -m 7192 is a good idea. You can probably reduce it a bit, like 4096.
* _-M 512 is too much_. 64MB should be more than enough for an
OpenSIPS listener on *any* scenario.
If you don't expect such traffic, then it looks like a denial of
service attack, case in which you should look into the *ratelimit*
module.

Hello Liviu,
The address table have 110 records, and the subscriber have 1738
records, i have 342 users registered
and im using the loadbalancer with 10 records
About recompile yes, i can recompile, i already have done this
before , you said that the logs that i send was ok, nothing like
a memory leak, but i can do, as i told you i change the memory
parameteres as you can see below
/usr/local/opensips/sbin/opensips -P /var/run/opensips.pid -f
/etc/opensips/opensips.cfg -m 7168 -M 512
im running now since March 1st .
