Hi group, We currently have 7 different Tx binds setup to our SMSC. We have been sending MT volumes of up to 3,000,000 messages per day at a rate of almost 200 / second. We've been doing this for more than a year now with no problems.
Suddenly about a week and a half ago, we noticed our throughput drop suddenly. The kannel status page shows we are only sending about 150 msgs / sec, but each of the 7 binds have over 50,000 MT messages queued. These queues eventually empty out, but some messages get delivered hours later than when they were sent by our platform. I am trying to troubleshoot this sudden drop in throughput and excessive queuing. The only thing I can think of is network latency between our network and the SMSC network. I don't know how to go about troubleshooting this though. Is there any other reason that might explain the sudden need for excessive queuing? Side question.....if kannel was restarted with so many MT messages queued for delivery, would they all be lost? Any assistance or tips for troubleshooting why so many messages are suddenly queuing would be extremely appreciated. Thanks, Jeff
