Logstash stops parsing after one entry

Elastic Stack Logstash
1

Hi,

I'm new to logstash and I'm having trouble parsing my logfile. Logfile (sanitized) can be found here:
http://pastebin.com/6nsSVMQj

There are three different types (outbound, inbound and "misc") of log entries in the same file, so I grok three different filters against the same message. My patterns are fine and when I change the order of entries in the logfile it still parses ok (but only the first entry)

My complete config looks like this:

input {
        file{
            path => "/home/steven/sip.log.2"
            start_position => beginning
            # logstash stores the lastrun=> so we trick it
            sincedb_path => "/dev/null"

            #if logentry does not start with date it's part of previous entry
            codec =>  multiline {
            pattern => "^\[%{TIMESTAMP_ISO8601:logdate}  \]"
            negate => "true"
            what => "previous"
    }

            }
    }

filter {
    grok {
            break_on_match => true
            match => {"message" => [
                    "\[%{TIMESTAMP_ISO8601:logdate}  \] %{LOGLEVEL:level}   AbstractLoggingInterceptor: Inbound Message\n----------------------------\n%{GREEDYDATA:id}\n%{GREEDYDATA:responsecode}\n%{GREEDYDATA:encoding}\n%{GREEDYDATA:contenttype}\n%{GREEDYDATA:headers}\n%{GREEDYDATA:payload}\n--------------------------------------"
                    ,"\[%{TIMESTAMP_ISO8601:logdate}  \] %{LOGLEVEL:level}   AbstractLoggingInterceptor: Outbound Message\n---------------------------\n%{GREEDYDATA:id}\n%{GREEDYDATA:responsecode}\n%{GREEDYDATA:encoding}\n%{GREEDYDATA:contenttype}\n%{GREEDYDATA:headers}\n%{GREEDYDATA:payload}\n--------------------------------------"
                    ,"\[%{TIMESTAMP_ISO8601:logdate}  \] %{LOGLEVEL:level}   %{GREEDYDATA:type}"]}

}
    }

output {
    elasticsearch {}
#       stdout {
#               codec => "json"
#       }
}

This is the result that I receive in elasticsearch. As you can see it's only the first entry in the logfile:

`[steven@localhost ~]$ curl -XPOST 'http://localhost:9200/logstash-2016.01.19/_search?q=*&pretty'
{
 "took" : 20,
  "timed_out" : false,
  "_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
  },
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ {
  "_index" : "logstash-2016.01.19",
  "_type" : "logs",
  "_id" : "AVJZ_BxC0rT1ILfRgQQB",
  "_score" : 1.0,
  "_source":{"@timestamp":"2016-01-19T13:03:58.412Z","message":"[2015-12-17 08:20:29,028  ] INFO   AbstractLoggingInterceptor: Outbound Message\n---------------------------\nID: 4911888\nAddress: https://baswebapp1:343/svc/Authentication.svc\nEncoding: UTF-8\nContent-Type: application/soap+xml; action=\"http://asp.net/ApplicationServices/v200/AuthenticationService/Login\"\nHeaders: {Accept=[*/*]}\nPayload: <test outbound>\n--------------------------------------","@version":"1","tags":["multiline"],"host":"localhost.localdomain","path":"/home/steven/sip.log.2","logdate":"2015-12-17 08:20:29,028","level":"INFO","id":"ID: 4911888","responsecode":"Address: https://baswebapp1:343/svc/Authentication.svc","encoding":"Encoding: UTF-8","contenttype":"Content-Type: application/soap+xml; action=\"http://asp.net/ApplicationServices/v200/AuthenticationService/Login\"","headers":"Headers: {Accept=[*/*]}","payload":"Payload: <test outbound>"}
} ]
  }
}

`

What am I doing wrong?
