Hi there, 1) I am using Kannel bearerbox II version cvs-20030404 2) It is the clean kannel.org version I got it from download page.
The emi2 SMSC does retransmit all queued messages, but sometime it received unrecognized message from socket, thus it disconnected and try reconnect after a long while. I am not sure what happened indeed coz I left the server on for overnight and client will continue using the service (More than 50000 messages per day sometime). And the next day, when I try to look into the log file and check on the store file, there are hundreds of messages stuck in the log and no re-transmitting activity going on for the next few hours. The log file is too big for me to be attached here so here is the last 2 debug message before the inactivity. 2004-01-16 11:55:56 [6] WARNING: EMI2[LocalLink]: received neither ACK nor NACK for message 0 in 60 seconds, disconnecting and reconnection 2004-01-16 11:55:56 [6] INFO: EMI2[LocalLink]: closing connection. All I can do is to stop the service and restart it again and the bearerbox will read the messages and start transmitting. And the emi2 server at the other side seems no stable enough to return the submit response each time a message is sent. This is all I can provide for now....

Please answer these questions: 1) which version of kannel? 2) is kannel patched by you or is it a clean kannel.org version? 3) if kannel patched by you then try clean CVS kannel.org version. 3) if this is not a CVS version try it first and see if a ?bug? still here. 4) if nothing of above descr. help, provide us with a more debug bearerbox output, because we can't guess what's going wrong having only 2 lines from the debug log... Thanks in advance for your help in kannel debugging!
