<tt>Hi, John!<br>
<br>
Transactions are stored in shared memory, not in the private one.
So the possible leak you are facing its not related to
transactions.<br>
During runtime, OpenSIPS might resize some internal structures,
which may lead to increase memory usage. However, after a while,
these allocations should stabilize</tt><tt>

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.<br>
<br>
Best regards,<br>

<div dir="ltr">I am using OpenSIPS (2.1.5 (x86_64/linux)) in

<div>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.</div>
