Hello,

right, very dummy paste position for resetting the redis context, use the attached patch or exchange lines 228 and 229. in redis_client.c

It works perfectly well now.:

ERROR: ndb_redis [redis_client.c:246]: error communicating with redis server [redis1] (127.0.0.1:6379/0): Connection refused

After recovering the redis server everything works as expected again.

Thanks,

Hi Daniel, Andrew

I've just tested the patch and kamailio crashes when the redis server is stopped. This is what I could get:

-From the logs:

Hello,

thanks for testing, indeed it was an extra declaration left over. Can you try with the new patch attached?

Cheers,
Daniel

I made a patch for server reconnect -- I had no access to a computer
with redis lib installed for the moment, hopefully it compiles. If you
can try and tell the result, it would be great, I can commit then.

I may be able to test this patch as well. Currently compilations bails
out on attempt to redeclare redisc_reconnect_server function parameter:

CC (gcc) [M ndb_redis.so] ndb_redis_mod.o
