Hi All, We are using kannel-1.4.4 as sms gateway. To send messages to kannel we are using kannel http url as we are using smsbox and bearerbox.
As we are using multiple kannel (smsbox and bearerbox), we are using AWS ALB (load balancer) in between our application and smsbox. We build kannel debian package and install the binary files in AWS opsworks infra on Ubuntu 14.04. The issue we are facing is, in a span of around one month of running fine one of smsbox used to not accepting the message and response with http code 502 bad gateway. But bearerbox is used to working fine as we are getting DLRs from SMSCs. We need to restart that kannel to bring the kannel working properly. The issue comes repeating to all the kannel instances in span of one month of working fine. Does anyone facing this issue. If yes how do they fix this issue? Please suggest what could be the possible reason/solution for this issue ?
