<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">Hi,</FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">I think that there is a memory leak with TLS. </FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">I have experienced it in my calls stress test, but it is possible to reproduce it easily with sipp with a simple scenario: </FONT></SPAN></P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">you have only to send REGISTERs in multi socket mode (-t ln). </FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">With this test I can observe the internal memory that sometimes increases (both for “TCP main” and the “TCP receivers” processes). </FONT></SPAN></P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">After some hours appears the messages:</FONT></SPAN>
</P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">WARNING:core:fm_malloc: Not enough free memory, will atempt defragmenation</FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">WARNING:core:fm_malloc: Not enough free memory, will atempt defragmenation</FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">ERROR:core:tcpconn_new: shared memory allocation failure</FONT></SPAN>
</P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">and Opensips is no longer able to accept new connections.</FONT></SPAN>
</P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">I wait some time (even hours) in order to free the allocated memory and then I start again the same test, but after some minutes the error appears again. </FONT></SPAN></P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">Note that:</FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">the Opensips config file is very simple, it performs only the “save” and then exits, without authentication or any other actions.</FONT></SPAN></P>
<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">I have tried to compile with the DBG_QM_MALLOC option, but I can’t see any difference compared to a normal situation.</FONT></SPAN>
<BR><SPAN LANG="en-gb"><FONT FACE="Times New Roman">I have tried also Opensips 1.8.1, but the memory leak is present also in this version.</FONT></SPAN>
</P>

<P><SPAN LANG="en-gb"><FONT FACE="Times New Roman">Thanks,</FONT></SPAN>
