Is this error appears too often?
Usually it is normal situation when SMSC drops connection.

The occurrence of this error has been reducing gradually from 4 times in a day to once in 2 days now. but i found a workaround.

Whenever a disconnection occurs, I force-restart the SMPP client with default values loaded and force a connection in 3 seconds.

Its works for now!
