Hi, please check your cluster definition: You requested parallel operations "8p" on the the connection, so it will write into con1 AND con2. What did you expect? ;-) "Command mode is a character among s, r and p. s is for doing serial operations (try first and if fails, try next); r is for doing round robin operations; p - is for doing parallel operations (this is valid only for write operations)." http://www.kamailio.org/docs/modules/devel/modules/db_cluster#db_cluster.p.… [4] Thanks, Carsten 2016-08-09 9:54 GMT+02:00 Jan Hazenberg <jenus(a)cyberchaos.nl>nl>: -- Carsten Bock CEO (Geschäftsführer) ng-voice GmbH Millerntorplatz 1 20359 Hamburg / Germany http://www.ng-voice.com [5] mailto:carsten@ng-voice.com Office +49 40 5247593-40 Fax +49 40 5247593-99 Sitz der Gesellschaft: Hamburg Registergericht: Amtsgericht Hamburg, HRB 120189 Geschäftsführer: Carsten Bock Ust-ID: DE279344284 Hier finden Sie unsere handelsrechtlichen Pflichtangaben: http://www.ng-voice.com/imprint/ [6] _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users [3]
