Hello all 🙂

I'm working with Logstash 2.3.4 and I'm facing a strange problem regarding the behaviour of the input feature.

Here's the situation :

I work with a very simple input configuration :  
input {  
file {  
path =\> "/var/log/\*/logs"  
start\_position =\> "beginning"  
ignore\_older =\> 0 # Also take existing older files  
sincedb\_path =\> "/opt/logstash/conf/since.txt"  
}  
}

Under /var/log, I have 2 objects for each application : one folder and one symbolic link pointing to that folder, say :  
the folder /var/log/appli1/ and the symlink /var/log/appli1\_ln/ pointing to /var/log/appli1/  
Under /var/log/appli1/ is located the log file I want to parse ( /var/log/appli1/logs)

As an output, logstash processes the entire file for each single line added to /var/log/appli1/logs, if i delete the symlink, logstash goes back to a normal behaviour and outputs a single line for each new line added to the log.

Could you please help, I cannot remove the symbolic links as they are part of the implementation of my work infrastructure.

Thank you.
