Hello, I have a gsm pool with 8 slots (with wavecom Q2406 chipset). Slots are connected via serial IC port to serial/usb switch (in case) and this pool is connected to PC via USB interface. Every slot is representing by serial port.
I am sending/receiving sms, receiving DLR. Everything work's fine, but sometimes (at some of days in month) are slots (not all) re-connecting or are in "stuck" state. This causes, that the sms are not sending and sometimes are the received sms "pushed" to the receiving URL manytimes. In kannel.log are log records like this one (only for "stuck" slot - others slot sending sms normaly): 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: TP-Validity-Period: 24.0 hours 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: --> AT+CMGS=147^M 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: <-- > 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: send command status: 1 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: --> 0051000C912460408793620000A797050003EE0202EAEAF4380D82CBC3E3B7DD9D0691CB6E1708B47CB7EBEEF4FA6D0FD34173903BDC4E83DA757D995E06BDC9F0B7BD4C4E83DC6110BD4E7F83A6CD29C85D16BF41EE30A8DC6A87D3EC3A28ED36BF01EDBAD9EC1AEB5D206B7A5C06A5DDE637C81D06DDEF7757BB6E36BBC67A17C81A9E839A55A311240D8FD3EE33885A0EB701 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: --> ^Z 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: <-- > 2017-09-08 17:27:12 [10868] [6] DEBUG: AT2[1]: <-- ERROR 2017-09-08 17:27:12 [10868] [6] ERROR: AT2[1]: Generic error: ERROR And this log records are in kannel.log when is received messaged "pushed" to receiving url manytimes: 2017-09-08 01:14:09 [10868] [6] DEBUG: AT2[1]: 3 messages waiting in memory 2017-09-08 01:14:09 [10868] [6] DEBUG: AT2[1]: --> AT+CMGR=1^M 2017-09-08 01:14:09 [10868] [6] DEBUG: AT2[1]: <-- +CMGR: "REC READ","+XXXXXXXXX",,"17/09/07,23:18:39+08" 2017-09-08 01:14:09 [10868] [6] DEBUG: AT2[1]: <-- V patek budu na Komenskeho 159.Zaslete hod.dodani..J.V. 2017-09-08 01:14:09 [10868] [6] ERROR: AT2[1]: got +CMT but pdu_extract failed 2017-09-08 01:14:09 [10868] [6] DEBUG: AT2[1]: <-- OK 2017-09-08 01:14:09 [10868] [6] DEBUG: AT2[1]: not deleted. To solve the problem is enough (very often) connecting to this slot via terminal (e.g. cu -l /dev/cuaU0 -s 115200) and enter command "AT" (that return "OK") and then close connection to this serial port. Sometimes solved this problem only restart of kannel.

What can cause these problems? -- Mira
