We have installed the latest version of Orion Context Broker ( 0.24 ) and execute it as a service but occasionally stops and any message appears in the log of the program.

Running dmesg we have discovered the following message:

  • In order to debug the problem, could you edit the question to include the following information, please? 1) the resquest messages that the CB receives since it is started until it stops, 2) how many subscriptions and registrations holds the DB, 3) operations system distribution and version, 4) tail of the /var/log/contextBroker.log file just after the fail , 5) memory consumption along time (e.g. just after starting CB, after 5 minutes, after 10 minutes, etc.) witch `ps v -p `. Thanks! – fgalan Oct 06 '15 at 08:24
