Crash of server

[Sebastien Carobbio]

Hello everybody,

I have a problem since 2 or 3 week with my gateway.

Sometime, the lora - server crash and I can't restart it.

the crash.log file contains:

2020-05-28 10:58:02 =CRASH REPORT====

  crasher:

Error in process <0.227.0> on node 'lorawan@fonroche-gateway-0001' with exit value:

Then sometimes,I have this message when I try to restart:

{"init terminating in do_boot",{{badmatch,{error,{lorawan_server,{bad_return,{{lorawan_app,start,[normal,[]]},{'EXIT',{{badmatch,{timeout,[rxframe]}},[{lorawan_db,ensure_table,3,[{file,"/home/travis/build/gotthardp/lorawan-server/_build/default/lib/lorawan_server/src/lorawan_db.erl"},{line,117}]},{lists,foreach,2,[{file,"lists.erl"},{line,1338}]},{lorawan_app,start,2,[{file,"/home/travis/build/gotthardp/lorawan-server/_build/default/lib/lorawan_server/src/lorawan_app.erl"},{line,18}]},{application_master,start_it_old,4,[{file,"application_master.erl"},{line,273}]}]}}}}}}},[{lorawan_app,start,0,[{file,"/home/travis/build/gotthardp/lorawan-server/_build/default/lib/lorawan_server/src/lorawan_app.erl"},{line,13}]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}

init terminating in do_boot ({{badmatch,{error,{lorawan_server,{_}}}},[{lorawan_app,start,0,[{_},{_}]},{init,start_em,1,[]},{init,do_boot,3,[]}]})

So, Can you help me please?

Have a good day!

Hello,

 

"timeout" on a database could be caused by an installation issue (new or old erlang?), or by a database corruption. Could you try if a fresh installation works?

Hello,

I have solved my problem in using this method:

- Delete all *.DCL files and rxframes.DCD file

- Change value of "retained_rxframes" by 1 in sys.config file

- Restart.

My GW have between 200 - 400 devices connected and I suppose that micro BDD used for display information in web page use these databases.

So I have another question: Is it possible to stop easilly the display of lora server?

Thank you for the support!
