If% p is specified, the process number will be entered.

### Confirmation method
```kill -sigsegv <pid>```Send a signal to the relevant process.

## Output core file
 Since core file output is disabled by default on Linux, it is recommended to enable core file output with ```ulimit -c unlimited``` before starting a Java application. However, be aware that if it occurs frequently, the core file will put pressure on the disk.

 Use ```ulimit -a``` to check what the current limit setting is. (```ulimit -c``` to check only the core file)
