<br>
Thank for your report - it will be better to push this via the
github tracker, the right place for coding issues:<br>

<p>Hi,</p>
<p>The OpenSIPS process gets stack in infinite loop when the
rtpengine module runs out of memory in send_rtpe_command()</p>
<p>Please review the following piece of code in rtpengine.c:</p>
<p><font face="monospace"> RTPE_START_READ();<br>
do {<br>
if (snode && snode->s) {<br>
if ((node = get_rtpe_node(snode, set)) == NULL
&& op == OP_OFFER)<br>
node = select_rtpe_node(ng_flags.call_id, 1,
set);<br>
snode = NULL;<br>
} else {<br>
node = select_rtpe_node(ng_flags.call_id, 1,
set);<br>
}<br>
if (!node) {<br>
LM_ERR("no available proxies\n");<br>
RTPE_STOP_READ();<br>
goto error;<br>
}<br>
<br>
cp = send_rtpe_command(node, ng_flags.dict,
&ret);<br>
} <b>while (cp == NULL);</b><br>
RTPE_STOP_READ();<br>
LM_DBG("proxy reply: %.*s\n", ret, cp);</font><br>
</p>
<p>When send_rtpe_command() returns NULL due to memory absence
here:</p>
<p><font face="monospace"> v = bencode_iovec(dict, &vcnt,
1, 0);<br>
if (!v) {<br>
LM_ERR("error converting bencode to iovec\n");<br>
return NULL;<br>
}</font><br>
</p>
<p>the mentioned loop ( <b>do {....} while(cp == NULL)</b> )
won't stop indefinitely causing the opensips process to become
stuck.</p>
