Segmentation Fault when more than one Values output

Client Libraries
1

Hello all, When I have more then one out I got a segmentation Fault as soon as I open the Device Values on the Dashboard

Here is my code… It crashes exactly at the ling “out[“PvFW”] = pvvaluesfwstr;”

thing["PvMonit"] << [](pson& out){
    myfile.open("/var/log/thinger.txt", ofstream::out | ofstream::app);
    myfile << currentDateTime() << " | Start PV Thing: " << endl;
    getPVvalues();
    out["PvPID1"] = pvvaluespidstr;
    out["PvFW"] = pvvaluesfwstr;
    out["PvSER"] = pvvaluesserstr;
    out["PvMOD"] = pvvaluesmodstr;
    out["PvSCS"] = pvvaluescsstr;
    out["PvACV"] = pvvaluesacvstr;
    out["PvV"] = pvvaluesvstr;
    out["PvAR"] = pvvaluesarstr;
    out["PvWARN"] = pvvalueswarnstr;
    myfile.close();
};

Any News on that? Do you need more Information and which one?

Hello @SecureXperts,

Unfortunately I’m not sure about what is happening here, maybe the RAM memory is overloaded. Have you tried with a shorter file or implementing less output keys in order to check that possibility?

Best regards
