File input stops reading file Logstash 1.5.4 windows

I have Logstash 1.5.4 running on windows 7
I have a syslog server writes to a logfile that logstash points to.
Config file:
# vi logstash-apache.conf

input {
file {
type => "syslogs"
path => "s:/*"
start_position => "beginning"
sincedb_path => "D:/logstash-1.5.4/sinceDB/syslog.db"
}
}
filter
{
if ([message] =~ /^#/) {
drop{}
}
if [type] == "syslogs"
{
grok {
match => { "message" => "%{YEAR:year}-%{MONTHNUM:month}-%{MONTHDAY:monthday} %{TIME:time},%{IP:SourceIP},%{SYSENTRY:Facility},%{SYSENTRY:Severity},%{GREEDYDATA:syslog_message}" }
add_field => [ "datetime", "%{time} %{month} %{monthday} %{year}" ]
}
date {
match => [ "datetime" , "HH:mm:ss MM dd yyyy"]
}
mutate
{
remove_field => [ "month", "monthday","time","year"]
}
}

}
output {
if "_grokparsefailure" in [tags] {
elasticsearch {
host => ES2907
protocol => http
index => "logstash-grokSyslogsfailure-%{+YYYY.MM.dd}"
}
}
else if [type] == "syslogs" {
elasticsearch {
host => ES2907
protocol => http
index => "logstash-syslogs-%{+YYYY.MM.dd}"
}
}

Logstash reads all 247 log files in s:/\* everything is ok, but when it is done it just stops reading the logfile from s:/\* even when the syslog server adds entries to the log file.

If i restart Logstash i picks up the sinceDB and reads the latest entries from the logfile and the stops again. Does it have anything to do with my s: windows mapped drive?

I have turned on the debug log at the last line reads:
