Daniel,
I have maximum 40 gateways to try. 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.
You are looping using two routes, thus for each gateway is counting
twice or more, depending on how exactly the conditions are there, plus
the other routes executed from main route to those looping.
Cheers,
Daniel

How many gateways you could possible try? More than 100?
Perhaps you can use a while loop instead of recursive subroute
executions.
Cheers,
Daniel

Daniel,
Attached will you find the graph.
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.

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

Daniel

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.

With the command “kamctl fifo get_statistics all” i get this:

Daniel,
I haven’t use the –m command.
I´m running kamailio 3.2.4 version.
The command kamctl stats is not available.

Hello,
how much shared memory have you allocated to kamailio? 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.
Cheers,
Daniel

Hi,
Last Friday I presented a increase of load in kamailio
by a client. The load was almost twice as usual. 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?
