relp input failed to load

hey,
Below is the output with the -vv flag. I'm getting those error without having a client connected to it(I'm planning to use rsyslog).
But very important to notice is that I'm using Keepalived to load balance the indexers, so I now realize that the errors that I see are due to a TCP check that the keepalived is doing to see if the logstash daemon is up.
I have the same setup with a tcp input ( "input { tcp { port => 5412} }" ) so I didn't thought it problematic...

Sounds like the relp server implementation we have doesn't safely handle a connection being closed.

Can you please capture the output with the -vv verbosity flag.
Also can you please describe how the log are shipped.
