We are getting the below exception while starting the logstash agent. Any one can help me please?

Thank you for the response. This issue got resolved. Issue is due to /tmp is mounted with certain mount options. After adding '-Djava.io.tmpdir=' to an other directory in logstash startup script, able to start the logstash agent. We are using the logstash from long time and recently we moved new H/W for hosting the services. Hence we faced this issue. As I mentioned after adding java.io.tmpdir we are able to start the agents. Thanks, Ravi ---
