hi, we have an LX40 that a SCADA system uses to send alarm messages. The users are telling me that they are getting text messages that are delayed by most of a day. I don’t know if they mean anything but when I look in the LX40 log I see lots of errors like this: Sep 25 16:08:09 info ALEOS\_CELL\_RadioTask: Starting sms thread… Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: SMS Buffer full Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: sendMsgToQCon failed (-4) Sep 25 16:08:10 err ALEOS\_SERVICES\_SMSPROC: Buffers apparently full when sending Is that a concern? Could any of this be a reason that SMS messages are delayed hours to days? ---

Hi @controlsystems, Welcome to our community! Could you please take a look at the below question/concern and share your answers? 1. How did you send and receive SMS messages? Did you use ACEmanager Web UI or AT commands? 2. Did you experience any SMS send and receive delays on the LX40 in the past? 3. What version of ALEOS and Radio module firmware is the LX40 running? 4. Please share the entire log file related to SMS receive delays and the template file with me. Thanks, ---

The messages are sent through an Ignition SCADA system, I don’t know how they do it. this is a new installation and my first time using one. Radio Firmware Version SWI9X07Y\_02.37.06.00 b91e64 jenkins 2020/06/02 00:54:15 |ALEOS Software Version|4.16.0| |ALEOS Build number|021| I can’t upload a file as I am a new user. I don’t think I should paste all 3000 lines in here ---

Hi @controlsystems, You can use the Message feature to send log file and template file by clicking on my name, selecting Message, just like how I am doing with your name. ![message forum](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/b/b0638f9a6f3311325c1a270b06aa053ac9875d00.png) Thanks, ---
