Note : Logstash instance was working fine for moderate load but when load increased drastically we are facing this issue and logstash is unable to come out of it. To avoid this
we have increased logstash congestion_threshold to 25 also increased -w to 10 for 4 core machine for logstash service still it is in same state.
