Hello, I am getting a strange behaviour while connected to a SMPP SMSC. Kannel is sending an enquire link each 60 seconds (as configured) but at a given moment it stops sending enquire links and after 6 minutes it complains about not receiving response from SMSC but it seems that really it is kannel who does not send the enquire link.
Here are the logs: Enquire link n: 2005-12-21 19:43:22 [30798] [7] DEBUG: SMPP[smpp1]: Sending enquire link: 2005-12-21 19:43:22 [30798] [7] DEBUG: SMPP PDU 0x81bb170 dump: 2005-12-21 19:43:22 [30798] [7] DEBUG: type_name: enquire_link 2005-12-21 19:43:22 [30798] [7] DEBUG: command_id: 21 = 0x00000015 2005-12-21 19:43:22 [30798] [7] DEBUG: command_status: 0 = 0x00000000 2005-12-21 19:43:22 [30798] [7] DEBUG: sequence_number: 1729 = 0x000006c1 2005-12-21 19:43:22 [30798] [7] DEBUG: SMPP PDU dump ends. 2005-12-21 19:43:22 [30798] [7] DEBUG: SMPP[smpp1]: Got PDU: 2005-12-21 19:43:22 [30798] [7] DEBUG: SMPP PDU 0x81bb170 dump: 2005-12-21 19:43:22 [30798] [7] DEBUG: type_name: enquire_link_resp 2005-12-21 19:43:22 [30798] [7] DEBUG: command_id: 2147483669 = 0x80000015 2005-12-21 19:43:22 [30798] [7] DEBUG: command_status: 0 = 0x00000000 2005-12-21 19:43:22 [30798] [7] DEBUG: sequence_number: 1729 = 0x000006c1 2005-12-21 19:43:22 [30798] [7] DEBUG: SMPP PDU dump ends.

Reconnecting. Here, kannel reconnects and all goes fine again. Regards and thanks for your help Alberto
