# Check app crash logs

Source: [https://docs.qualcomm.com/doc/80-41102-1/topic/Check-app-crash-logs.html](https://docs.qualcomm.com/doc/80-41102-1/topic/Check-app-crash-logs.html)

Check the latest app crash logs or core dumps in either a persistent or non-persistent location.

When a process within an app faults or exits in error, a copy of the current syslog buffer is captured along with a core file of the process crash (if generated).

The core file maximum size is determined by the process settings
        `maxCoreDumpFileBytes` and `maxFileBytes` found in the
      processes section of an app's .adef file. By default, the
        `maxCoreDumpFileBytes` is set to 0, don't create a core file.

To help save the target from flash burnout, the syslog and core files are stored in the RAM FS under /tmp. When a crash occurs, the following directory is created:

    /tmp/telaf_crash_logs/Copy to clipboard

The files in that directory appear as follows:

    core-myProc-1418694851
    syslog-myApp-myProc-1418694851Copy to clipboard

To save on RAM space, only the most recent four copies of each file are preserved.

If the fault action for that app's process is to restart the target, the output location
      is changed to the following: 

    /data/telaf_crash_logs/Copy to clipboard

 The most recent
      files in RAM space are preserved across reboots.
