Re: [SR-Users] too many recursive routing table lookups

Daniel, Is there a limit of times that one can invoke next_gw() function without relaying the call? Can these be the problem?

That's why this error is strange. Indeed the error is presenting in calls having no more than 12 retries ( because of channel exceed or failure messages) before they could be relay (see the attached file). So I don't understang why is the error is appearing if I don't reach 100 recursive executions.

More than 100? Perhaps you can use a while loop instead of recursive subroute executions.

I don't really understand much of it. My route CHANNELS is where I check if the gateway is full, if that is the case , a go back to RELAY route , load next_gw() and then look for the channels capacity from the new gateway . If I received a failure response , I load next_gw and check for channels.

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 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?

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?
