Dialogic board: GctException: Could not Get GCT message

[vetss]

When a Dialogic board is down or congested (I am not 100% sure that this is a congestion case but may be) we can have the mentioned lower Exception.

The Exception occurs in the method Mtp3UserPartBaseImpl.sendMessage(Mtp3TransferPrimitive msg) in code line: GctMsg txMsg = GctLib.getm(buf.length);

So it's looks like we have a lack of GctMsg messages to obtain from the board. How to solve:

• try to get statistic / board state from the board to understand what really happens
• capture Exceptions or / and check a board's state and buffer then unsent messages.
• If too many messages in such case - we will possibly need to care of
  • control of a board state active/prohibited (and generating like MTP-PAUSE)
  • congestion control.
