Hi Daniel
both values are null.
ok, could be a hint that the connection is down and try a reconnect...
I might have found something: apparently some of the sockets
kamailio->redis were inactive for a while and were being closed in the
redis end.
Do you know if there is a keepalive mechanism that reddis offers, or a
command to set the timeout value from the client side?
Cheers,
Daniel
This is redis default config:
# Close the connection after a client is idle for N seconds (0 to disable)
timeout 600
I've set the timeout value to 0 to confirm if this is actually the
problem.
In case it might be useful for somebody, we've used lsof in recurrent
mode to monitor the sockets status:
server# lsof -i :6379 -r 5"m===%T===" | grep -e == -e kamailio

Hi all
I have started making some tests with the ndb_redis module. So
far we have not stressed the module (no more than 5 HGET
commands/second at maximum). It works well, but with at some
point it starts failing. The failures are easily found because
the logs always show this:
INFO: <core> [main.c:811]: INFO: signal 13 received
this due to a broken connection. What do you get in redis reply
and info variables?
After that the redis value is always null. If I restart
kamailio it starts working again.
I've run kamailio with debug=4 but I haven't seen more useful
information. On the redis side, I could find nothing in the
logs either, the number of clientes connected is alway much
less than the configured maximum, Any idea?
On the other hand, if I restart redis we need to restart
kamailio to restore the connections. Is the reconnection to
redis on the roadmap?
It should not be that complex, there is the code for initializing
the connection, it should be reused for doing it again in case of
failure.
Cheers,
Daniel
