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

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