From a tech support email:


Who can help me debug an issue I’m having with my Now server we have on our 3GPP system. We are running a high volume of messages daily and this is causing many messages to get backed up in the message queue.

How can I configure to eliminate excessive delivery attempts, we want to set for only two delivery attempts
We want to purge the message daily

Can someone advise what to configure and forward me an example of the config?



Configuration settings related to retry settings can be found here:

Pay particular attention to the RetryMaxAttempts and RetryMaxAge settings.

That article contains some information specific to the SMPP protocol (such as references to specific error codes, however the retry settings apply to all types of SMSC connections.

To debug these issues, I would start with the SMSOUT-yyyymdd.LOG file, which will record the errors.

If you need more detail, enabling the SMSDEBUG.LOG (checkbox on Serial # page) can sometimes be helpful...and in some situations Wireshark can be extremely helpful.
