Also, it might be useful to see if you normally have full receive buffers like
above or only when the issue is observed, running netstat in loop, something
like below:

while sleep 5; do 
  t=`date '+%F %H:%M:%S'`;
  netstat -na | grep 8457 |
  while read l; do 
    echo "$t $l";
  done;
done > /tmp/netstat.log
