<p><tt>Hi, Rodrigo!</tt></p>
<p><tt><br>
</tt></p>
<p><tt>Valgrind may report some memory allocated, and not freed, but
that is not necessarily a memory leak. There is a single block
of 1024 bytes not freed during runtime, so I think that is
peanuts. The memory used by OpenSIPS is not allocated with
malloc, so cannot be traced by valgrind.<br>
</tt></p>
<p><tt>Regarding the system memory, it is normal to decrease as
OpenSIPS uses that memory during runtime. However, after some
time, this should </tt><tt>
<meta http-equiv="content-type" content="text/html;
charset=UTF-8">
stabilize. Anyhow, sometimes the system memory might generate
false alarms, so if you are tracing any memory leaks, you should
check OpenSIPS's internal statistics.</tt></p>

<p>Hi.</p>
<p><br>
</p>
<p>Does someone here is getting/handling memory leaks with

<p>I'm using newest commit from OpenSIPS 2.2 and newest version
of SQLite.</p>
