One Logstash shipper on windows 2012 frequently keeps crashing


I've one Logstash shipper service (Logstash 1.5.6) keeps crashing. Below is the log and configuration. Anyone has any clues? Thanks a lot!

The logstash configuration (of course the actual configuration contains multiple file input modules):
input {
file {
type => "ApplicationA"
path => ""
add_field => ["logkey", "xxxx"]
output {
redis {
host => ""
data_type => "list"
key => "%{logkey}"
