Hi list,

I'd like to suggest a different approach while handling the following:

2006-02-06 11:57:34 [542] [23] ERROR: SMPP[foobar]: SMSC returned
error code 0x00000058 (Throttling error) in response to submit_sm.

when it appears in series. Which means obviously the 15 second wait period does 
not give SMSC enough time to "throttle down" our connection and allow us to send 
messages again.

How about having here an exponential back-off for the waiting period, meaning:

  error code 0x0058
  wait 15 sec.
  error code 0x0058
  wait 30 sec.
  error code 0x0058
  wait 60 sec.

or a linear raiso of the waiting period?

Stipe
