I am using a single Logstash config file for multiple file inputs and grok filters and single ES output. The problem is that, it goes in infinite loop and I don't know why. I created separate files to check on if GROK is working fine for respective logs and it works fine. Then I merged the content and did configtest as well.  
Logical part:  
#----------Start-----  
input {  
file {  
#TypeA  
#path for file A  
}  
file {  
#TypeB  
#path for file B  
}  
}

filter {  
if [type="A"] {  
#GROK for A  
}  
}

filter {  
if [type="B"] {  
#GROK for B  
}  
}

output {  
elasticsearch {  
#output config for elasticsearch  
}  
}  
#----------End-----

Please guide me for same

Can you elaborate, what do you mean here?

I am running logstash manually i.e. (logstash -f /path/to/config/file -v). And after I execute the commad I can see all the logs getting parsed and it continues unless I stop it manually. Also there is no index created in ES for the logs being parsed.

I think you are experiencing the ignore\_older feature.

By default the file input will ignore any files that are older than 24 hours.

Add `ignore_older => 0` to disable this feature.
