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.
Best regards,

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
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?
