<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Calibri","sans-serif"">Hi Nicolas,<br>
<br>
I received that report a month ago:<br>
<br>
"we have found the OGROCISession is never released, causing a large memory leak whenever a connection is closed.
<br>
As workaround, we added in O</span><tt><span style="font-size:10.0pt">GROCISession::~OGROCISession()</span></tt><span style="font-family:"Calibri","sans-serif""><br>
<br>
</span><tt><span style="font-size:10.0pt"> if( hEnv )</span></tt><span style="font-size:10.0pt;font-family:"Courier New""><br>
<tt> OCIHandleFree((dvoid *) hEnv, (ub4) OCI_HTYPE_ENV);</tt></span><span style="font-family:"Calibri","sans-serif"">"<br>
<br>
But they also mention some other memory leaks without an specific location on the code.<br>
<br>
Can you try to see if that fix the problem?<br>
<br>
Thanks,<br>
<br>
Ivan<br>
