Thanks for the quick response!
I am asking the operator to get me logs from the SMSC to see if there were throttling errors. About backend side, we are discarding DLR requests, and we have separate applications for sending and receiving the messages, so I dont think the error might be there. But, anyway, shouldnt it be delaying everything instead of just delaying that 22k chunk?

Without detailed smsc.log you can't really say what was wrong. It might be your backend software not handling properly this large chunk of requests (e.g. untuned apache2 might be failing to serve DLR requests from kannel) or your SMSC operator giving you throttling errors. Generally speaking 22k of MT messages in the range of 10 minutes means you need to send ~37 MT per second which is not that much actually. 2014-02-21 1:17 GMT+04:00 Germán Bobr - Redmond Software <german.b...@redmondsoftware.com>: Hi, I have a kannel installation under some traffic, sending and receiving SMS through an SMPP connection. Yesterday we had a campaign running between 05:15 PM and 05:25 PM wich generated a big chunk of 22k SMS, added to the regular daily traffic. We found that some of the messages enqueued between 05:15 PM and 05:25 PM were highly delayed, in some cases not being delivered until 10 PM. Whereas messages generated after 5:25 PM were sent without any delay. Our outgoing messages are not using priorities, all our traffic is generated with priority=0. I see the messages on smsbox.log at the original time (5:15-5:25) but in core.log, I see some of them being sent several hours later. Can you help me figure out whats happening?
