SMSC - Maximum retries for message exceeded, discarding it!

Hi guys,

I noticed strange behavior of bearerbox (SMSC side of it) that most likely
have been occurring for some long time but I just noticed it.

In smsc log i see following warning message:

"Maximum retries for message exceeded, discarding it!"

and it comes right after submit_sm_resp that has an error from SMSC within
it, for example:

The "0x00000008 (System Error)" is ok, we know what this error means and
how to process it.


I searched a lot about this warning message over the internet but couldn't
find anything.


Is there anyway to overcome this issue maybe?
