Fluentd stops sending syslogs to elasticsearch

[srujith07]

Please help !!!!!

Fluentd stops sending syslogs to elasticseearch automatically after sometime, there is no error showing up in fluentd logs everything looks fine there.

If i restarted my td-agent.service the logs are coming for sometime in the elasticsearch after 3-6 mins they are getting stopped automatically and no error is showing in td-agent logs.

Here is my configuration:

<match "mytopicname">
      @type elasticsearch
      hosts        "my_IP_address_here"
      ca_file       "my_path_here"
      client_cert  "my_path_here" 
      client_key  " my_path_here" 
      ssl_verify  true
      user   "my_username"
      password "my_password"
      logstash_format true
      logstash_prefix "my_index_name"
      logstash_date_format  my_date_format
      time_key_format  "my time format"
      type_name  fluentd
      log_es_400_reason true
      include_timestamp true
      reconnect_on_error true
      reload_on_failure true
      reload_connections false
     <buffer>
          @type file
           path     "my path here"
           chunk_limit_size 10m
