Intermediate logstash shut down stops indexing after the restart

Elastic Stack Logstash
1

I was indexing 110GB of data to elastic search using logstash.
after it ran for few hours, i realised , i need to add another conf file for a different indexing. so i decided to add the same and restart logsatsh. when i restarted, the indexing wouldnt start and it keeps saying the below in logs.

"{:timestamp=>"2016-05-10T17:01:14.124000-0700", :message=>"Reached open files limit: 4095, set by the 'max_open_files' option or default, files yet to open: 83634", :level=>:warn}".

Please help if i miss something.
