Hi,
On Logstash 5.6 I have following working config.
```
input {
tcp {
port => 514
type => syslog
}
udp {
port => 514
type => syslog
}
}
filter {
if [type] == "syslog" {
grok {
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
add_field => ["received_from", "%{host}"]
}
}
}
output {
elasticsearch {
hosts => ["127.0.0.1:9200"]
}
stdout { codec => rubydebug }
}
```
When I am using same config on logstash 6.7 I get following error:
```

Can you please help me to identify and fix this problem ?

That suggests that logstash is reading jvm.options as part of the logstash configuration. What command line are you using to start logstash? Are you trying to use -f or pipelines.yml?

Yes, that was the problem. I had placed my logstash-syslog config in logstash config dir where jvmoptions and other files exist. Now I have created another dir within config as conf and have moved logstash-syslog config in config/conf and I am able to start process successfully.
Thanks for pointing it out.
