@magnusbaeck  
Now i know what you meant - multiline is not needed for this configuration when i get complete JSON message in log in single line.

After further investigation seems like reading via NFS causes this problem.

So I'll contiune in thread  
[https://discuss.elastic.co/t/logstash-codecs-multiline-json-parseerror-illegal-character/115292](https://discuss.elastic.co/t/logstash-codecs-multiline-json-parseerror-illegal-character/115292)  
if needed.
