Hi Team,

My logstash was working completely fine till yesterday and suddenly it stopped working, now when I am trying to restart it using **systemctl start logstash** command , I am getting below error.

```
 Check your env for conflicting versions of SnakeYAML

it is because you don't have permission on /tmp to create a dir.  
it will try to create a dir called ls\_temp

jvm.options file has this. set this up properly, you can change to different dir if you like

## JVM temporary directory

#-Djava.io.tmpdir=${ES\_TMPDIR}
