<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:11.0pt">We have recently upgraded to OpenSIPs 2.3.3 and after deploying to our production environment we have found a significant memory leak. The leak is being reported
by OpenSIPS’ statistics only; the used memory of the machine itself is not increasing.</span><o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:11.0pt">I believe I have been able to reproduce the leak with locally testing with a relatively small number of transactions. These stats are from opensipsctl get_statistics
command for the shmem group. You can see the used memory is increasing linearly with every set of transactions:</span><o:p></o:p></span></p>

it to take manual action prior to compile. Will the process described on that page for OpenSIPS 1.7 still work in 2.3.3? Can I manually edit the Makefile.defs as described? Once I have this enabled, what logs do you need?</span><o:p></o:p></span></p>
