This is when you have a recursive loop or too many chained subroutes
executed. Like:<br>
<br>
request_route {<br>
route(x);<br>
}<br>
<br>
route[x] {<br>
route(y);<br>
}<br>
<br>
route[y] {<br>
route(x);<br>
}<br>
<br>
if you have sources of kamailio, then you can check with:<br>
<br>
./utils/route_graph/route_graph.py /path/to/kamailio.cfg<br>
<br>
See if you can spot the loop.<br>
<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Indeed,
“kamctl fifo get_statistics all” is the same as "kamctl stats"
in newer versions.<br>
<br>
You run with default 32MB which is rather low, imo. You have
less than 1MB free at this moment.<br>
<br>
Start kamailio with larger memory, like -m 512. It is not
going to be taken from the system unless kamailio is really
using it.<br>
<br>

<br>
how much shared memory have you allocated to kamailio? In
other words, have you given any value via -m command line
parameter?<br>
<br>
You can see it also via:<br>
<br>
kamctl stats<br>
<br>
Look for shmem fields.<br>
