Hi Guys,

I have a problem parsing a simple csv-file with logstash and the csv filter.  
The parsing works fine until a certain point. I have all fields present that I would exspect. As I want to visualize this data in Kibana especially the numerical data, I did learn from my past experience with logstash that you have to explicit convert your present fields from Strings to Integer.  
So far so good.

My filter looks like this:  
filter {  
csv {  
columns =\> ["project","id","mantis-link","summary","status","category","target\_version","relations","relCount"]  
separator =\> ","  
skip\_empty\_columns =\> "false"  
}  
if [relCount] {  
mutate {  
convert =\> ["relCount", "integer"]  
}  
}  
}

This works fine.  
BUT if the value of the relCount field ist greater than 9, i get a csv-parse failure and I have no clue why. I can reproduce it every single time.

Thanks in advance and I appreciate your help.
