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

I have another ERROR that is presenting:
“WARNING: too many recursive routing table lookups (101) giving up!”
I have a routing diagram that includes max number of channels per gateway. The dialog module keeps track of the number of channels use by active calls ( set_dlg_profile, get_profile_size) and if a gateway has reached his maximum , I search for next_gw().
This recursive mechanism can be made several times if many gateways of one route are full.
But I analyzed the error and I have maximum 24 repeats of this process per call, never reach 100 repeats as shown by the ERROR.
Can the maximum value of recursive lookups be the sum of lookups counting all the early dialogs?

Camila

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

In other words, have you given any value via -m command line parameter? You can see it also via: kamctl stats Look for shmem fields.

By that time I encountered with many issues in kamailio. The calls were not relay to gateways, and a lot of messages about memory were appearing in log file. Kamailio didn’t crash. When I remove the extra traffic all went back to normal. Is there a issue about memory leak or about to few memory resources to manage this amount of traffic?
