Mbed 6LoWPAN gateway problem #82

Closed ghost closed 7 years ago

ghost commented 8 years ago

Hi all,

Just to have a whole picture: I have build 6LoWPAN Thread network with 5 nodes. I created additional resource (temperature) in the client code. After some time (period cca. 1 day) system stops. Serial communication with gateway stops. You can see this in log files: serial_GWNOK*.log As the problem is probably in the gateway, trying to reach devices directly trough https://connector.mbed.com/, does not help (0 devices discovered).

You can filter working time of the system with the help of demo2.html I also attached log file of mbed_connector_api.py: connector_api_err_13_07.log If you will search the file by timestamp, format of the timestamp in the file is like 2016-07-06 10:09:49.

I'm using gatewayThreadDynamic.bin.

What could be the cause?

Thanks, Primoz Zajec log_files.zip

Hi, Sorry for long delay and thanks for reporting this issue. It looks like there is a memory leak in the border router. Logfile "serial_GW_NOK_12_07" contains few "out of memory" and "No mem" lines before the gateway stops working. Best Regards, Arto

Status check done and planning done howto proceed/solve this issue. So far we haven't had enough bandwidth to build similar testing setup for this sample application.

Hi,

I was not able to reproduce the problem using the new gateway binaries available in https://github.com/ARMmbed/mbed-os-example-client/tree/master/GW_Binary. After 1 day of usage no memory leak was detected and memory consumption was steadily between 21-22kBytes while peak memory consumption was 26kBytes. I didn't try with old binaries that were originally used in this issue.

@LTEKuser01 , would you be able to try again with the new gateway binaries? If the problem still persists then we could arrange a special gateway binary that has more traces turned on to pinpoint the leak location.

Best regards, Arto

Hi,

Closing this issue as we can't reproduce the error with the new gateway binaries available in https://github.com/ARMmbed/mbed-os-example-client/tree/master/GW_Binary.

This repository is superseded in mbed OS 5.2. Please file a new issue to repository https://github.com/ARMmbed/mbed-os-example-client if issues are found from border router binaries.

Best regards, Arto
