Ok, so it is the first listener for the private IP that leaks. Next, is
the memory stabilizing in time? Or it is continously decreasing?
Yes, that's how you should make the dump.

Dear Razvan,

Process:: ID=8 PID=17359 Type=Timer handler
1.1.1.1 is public IP (I changed). The decrease in memory I see is for
Process:: ID=7 PID=17358 mainly. My call flow is as following
- New Invite hits the opensips on 1.1.1.1:9094 <http://1.1.1.1:9094>
- Apart from message validity checks I query DB to check if its a
valid user (Using local cache also there)
- Create dialog, Topology_hiding functions are called along with some
avp population
- Using dispatcher ds_select_domain Call sent to udp:192.168.45.2:7060
<http://192.168.45.2:7060> (using force socket). This
192.168.45.2:7060 <http://192.168.45.2:7060> is actually freeswitch
- Call again comes back to opensips on udp:192.168.45.5:5064
<http://192.168.45.5:5064>
- New dialog is created and topology_hiding is called
- Drouting function do_routing is called which tries one gateway and fails
Dump i need to create with memlog=4 memdump=1 right?

Hi, John!
Transactions are stored in shared memory, not in the private one.
So the possible leak you are facing its not related to transactions.
During runtime, OpenSIPS might resize some internal structures,
which may lead to increase memory usage. However, after a while,
these allocations should stabilize.
Can you post the output of the kill -SIGUSR1 on pastebin so we can
take a look? Also, what type of process is the one you are seeing
the leak into? You can find out using the 'opensipsctl ps' command.

I am using OpenSIPS (2.1.5 (x86_64/linux)) in production. I
observed private memory is decreasing constantly for one process
mainly and ultimately leading to memory errors and crash.
To debug this issue I prepared a test server and compiled
opensips as per
https://www.opensips.org/Documentation/TroubleShooting-OutOfMem
<https://www.opensips.org/Documentation/TroubleShooting-OutOfMem>
I made only one single call (which was rejected by opensips as it
was not authorized user) and I saw private free memory decreased.
I was hoping since transaction is done ideally it should release
memory and should show me same memory as startup but it did not.
I verified this with many call attempts and i see free memory is
always decreasing slowly.
I used kill -SIGUSR1 <lowest pid> to create memory dump. But i am
unable to make sense of it. It shows log like ...

I pasted only few lines in this mail. What should be my next
step?...How can i really trace what is wrong in my script or any
other memory leak?
