Hi, I've got a kannel install with emi smsc connection. When we send lots of sms to the smsc at once the delivery notifications only come at the end when kannel's queue is empty. Smsc only accepts 10-15 SM/sec but can send back horrible amount at once. This is a problem for us because kannel gets thousands of dlrs in one second and ERROR messages appear in smsbox.log:

I don’t know why it is happen but there must be some kind of limit (I think it is not an open file issue but something similar). Maybe there is another side effect (but I’m not sure yet) in connection with DLR database because the number of SMs that are not in the end phase (delivered or can’t be delivered) are growing.
