Hi Team,

I have been encountered with the below issue when trying to update some alarm details in confd db.  
Below is the logs for the same.

```nohighlight
TRACE Connected (maapi) to ConfD
TRACE MAAPI_START_USER_SESSION --> CONFD_OK
TRACE MAAPI_START_TRANS --> CONFD_OK
TRACE MAAPI_EXISTS /ME/AlarmList{0} --> CONFD_OK
TRACE MAAPI_EXISTS /ME/AlarmList{0}/AlarmRecordGrp{57382 PLATFORM_0} --> CONFD_OK
TRACE MAAPI_CREATE /ME/AlarmList{0}/AlarmRecordGrp{57382 PLATFORM_0} --> CONFD_OK
TRACE MAAPI_GET_ELEM /ME/AlarmList{0}/numOfAlarmRecordsDEBUG item does not exist - /ngnrm:ME/AlarmList{0}/numOfAlarmRecords does not exist
 --> CONFD_ERR
TRACE MAAPI_CREATE /ME/AlarmList{0}/numOfAlarmRecordsDEBUG item is not creatable -

TRACE MAAPI_SET_ELEM2 /ME/AlarmList{0}/numOfAlarmRecords --> CONFD_OK
TRACE MAAPI_SET_ELEM2 /ME/AlarmList{0}/AlarmRecordGrp{57382 PLATFORM_0}/alarmType --> CONFD_OK

TRACE MAAPI_SET_ELEM2 /ME/AlarmList{0}/AlarmRecordGrp{57382 PLATFORM_0}/alarmRaisedTime --> CONFD_OK
TRACE MAAPI_EXISTS /ME/AlarmList{0}/AlarmRecordGrp{57382 PLATFORM_0}/clearUserId --> CONFD_OK
TRACE MAAPI_EXISTS /ME/AlarmList{0}/AlarmRecordGrp{57382 PLATFORM_0}/alarmClearedTime --> CONFD_OK
TRACE MAAPI_SET_ELEM2 /ME/AlarmList{0}/lastModification --> CONFD_OK
TRACE MAAPI_APPLY_TRANS DEBUG external error - application communication failure
 --> CONFD_ERR
TRACE MAAPI_STOP_TRANS --> CONFD_OK
TRACE MAAPI_END_USER_SESSION --> CONFD_OK

```

In the mean time i have check the devel.log in netconf server, i have seen the below line is printed.

```nohighlight
<INFO> 23-Nov-2022::05:40:50.797 du-oam-server-6f749c4d8b-c8bpw confd[33]: confd Getting delta diff, no alt-name: true

```

Can you please let me know what is the reason of getting “application communication failure”.

Thanks  
Nishant Kumar

“Application communication failure” means that a daemon (e.g. a data provider) did not respond as ConfD expected - sent an invalid response or did not respond at all. You should definitely see more in devel.log, in particular if you set `/confdConfig/logs/developerLogLevel` to `trace`.

Hi ,

Thanks for the update.  
But i am not able to see any fileld like " `developerLogLevel`".

i can see only the below section in our conf file.

```auto
<developerLog>
      <enabled>true</enabled>
      <file>
        <enabled>true</enabled>
        <name>./devel.log</name>
      </file>
      <syslog>
        <enabled>false</enabled>
      </syslog>
    </developerLog>

```

Keep developerLogLevel under “logs” section as follows

```auto
<logs>
<developerLog>
...
</developerLog>
<developerLogLevel>trace</developerLogLevel>
...
</logs>

```
