We have the Environment Logstash with input plugin as "TCP-input plugin" And output to file.  
And we are sending syslogs using rsyslog to logstash tcp input plugin .  
But intermittently(after 5 to 6 hours) we are getting  
[ERROR][logstash.inputs.tcp] Error in Netty pipeline: java.io.IOException: Connection reset by peer

When we are getting this issue,we are reduction in throughput

We are using Logstash 6.8.3  
TCP input plugin 5.2.2  
TCP input plugin mode:server  
TCP keep Alive: false

Can you please help on this.What is the reason for that?And how to fix it.
