Hi! Please advise. First I have all the messages with the following error "ERROR: Message Queue Full -- SMPP -" and then the following error "- ERROR: System Error -- SMPP"
When I restart the servise all the situation seems to be okay - The messages accumulated in the "Q" begin to send normally. What does it mean?

Hi Stefan,

Those errors are being returned from your SMS service provider.

We are simply reporting the SMPP error code that is being returned by the SMS service provider when we attempt to submit a message.

"Message Queue Full" (ESME_RMSGQFUL) is somewhat common, and it is intended to mean that the message queue is full at the provider, and no more SMS messages can be submitted.

NowSMS behaviour here is to delay, and then retry.

"System Error" indicates that the provider is returning an SMPP error response code of ESME_RSYSERR.

I cannot see any reason why the provider would return this error unless something is very wrong with the provider's system.

What is puzzling, however, is that restarting the service resolves the problem. I don't have any explanation for that.

You might have to ask your SMS service provider why you are encountering the following SMPP error responses from their system:

ESME_RMSGQFUL - "Message Queue Full"

ESME_RSYSERR - "System Error"

Perhaps they have some sort of limit defined on your account, where you are only allowed to submit so many messages per connection.

You might want to enable the SMS debug log, so that we can look, in particular, at the SMPPDEBUG.LOG, to see if that provides any clues. Feel free to e-mail that to nowsms@now.co.uk, and reference this thread, so we know what we're looking for.

We could try adding a configuration parameter to force a re-bind to the SMPP provider after receiving a "system error" response. That's about the only potential solution that I could think of ... but I think you should find out from your provider what they think the problem is.

Stefan,

One more idea ... see the thread referenced below for how you can set a throttling level for how quickly we will attempt to submit messages to the SMSC:

Perhaps you are sending messages faster than they will accept them, and their system does not handle this gracefully.
