Queue empty error.

[NickAskew]

Hi Alt,

I am receiving the exception below when I am stress testing the SMPP Server component. I am receiving approximately 250 SubmitSm's per second from a single ESME, and delivering DeliverSm's back to it using SmppServerClient.Deliver within another thread at approximately the same rate.

System.InvalidOperationException was unhandled
Message=Queue empty.
Source=System

Hi Alexey,

Further information:

The error still occurs even when I don't do any work in the SmppServer events - it happens after receiving 10000+ submissions which have been sent at around 400 per second. It isn't related to me sending the same client DeliverSm's.

Regards

Nick

Hi Nick

I added workaround in version 1.0.12.3.
Please try it again.

Thank you.
