Logstash stopped when received x line and not push to elasticsearch

[yannice92 (Fernando Yannice)]

I have 2 server. server log and server logstash
I using only logstash 6.8 and elasticsearch (without filebeat)
from server log I send the log to server logstash using cron.
and in server logstash I have multiple pipeline.
for log I'm using this config

    input {
      file {
        path => ["/home/xxxxxx/bcp/bcp_usage_home_lte_*.txt"]
        start_position => "beginning"
        sincedb_path => "/etc/logstash/dbpath/usagestatistic.db"
      }
    }

    filter {
      grok {
        match => {"message" => "(?<DATE>[0-9]+)\|(?<MSISDN>(.)+)\|(?<APP>(.)+)\|(?<CATEGORY>(.)+)\|(?<DEVICE>(.)+)\|(?<VENDOR>(.)+)\|(?<APN>(.)+)\|(?<TETHER>[0-9]+)\|(?<QUOTA>[0-9]+)"}
        remove_field => ["message"]
      }
      mutate {
        convert => {
          "QUOTA" => "integer"
          "TETHER" => "integer"
        }
      }
    }

    output {
      elasticsearch {
        hosts => ["1.2.3.4:3306"]
        user => "user"
        password => "xxxxxxxx"
        ssl => true
        ssl_certificate_verification => false
        index => "usagestatistic"
      }
      stdout { codec => rubydebug }
    }

and for pipelines.yml

    # This file is where you define your pipelines. You can define multiple.
    # For more information on multiple pipelines, see the documentation:
    #   https://www.elastic.co/guide/en/logstash/current/multiple-pipelines.html

    - pipeline.id: usagestatistic
      path.config: "/etc/logstash/conf.d/usagestatistic.conf"
      queue.type: persisted
      pipeline.workers: 2
    - pipeline.id: customer_data-activity
      path.config: "/home/xxxxxx/customer-data/activity.conf"
      pipeline.workers: 1
      #queue.type: persisted
    - pipeline.id: customer_data-delivery
      path.config: "/home/xxxxxx/customer-data/delivery.conf"
      pipeline.workers: 1
      queue.type: persisted
    - pipeline.id: customer_data-profile
      path.config: "/home/xxxxxx/customer-data/profile.conf"
      pipeline.workers: 1
      queue.type: persisted
    - pipeline.id: customer_data-payment
      path.config: "/home/xxxxxx/customer-data/payment.conf"
      pipeline.workers: 1
      queue.type: persisted
    - pipeline.id: customer_data-order_fullfillment
      path.config: "/home/xxxxxx/customer-data/order_fulfillment.conf"
      pipeline.workers: 1
      queue.type: persisted
    - pipeline.id: customer_data-order_fulfillment_history
      path.config: "/home/xxxxxx/customer-data/order_fulfillment_history.conf"
      pipeline.workers: 1
      queue.type: persisted

when I check the log I cannot see any error so I think it's not problem with the config files.

[2020-08-17T14:57:53,751][DEBUG][filewatch.tailmode.handlers.grow] read_to_eof: get chunk
[2020-08-17T14:57:53,752][DEBUG][logstash.inputs.file     ] Received line {:path=>"/home/xxxxxx/bcp/bcp_usage_home_lte_20200815.txt", :text=>"20200815|628123456789|BranchMetrics|DeviceServices|unclassified|unclassified|home|1|142705"

these logstash-plain.txt print end of line log bcp_usage_home_lte_20200815 but not push to elasticsearch.

when I kill the logstash and start again it running well with output to ES. but tomorrow I check again the next log it received to logstash but stop at x lines. and I tried to restart the logstash and it's happened again.
