Broken Pipe Error on 1 Server

[Joshua Brodie]

Out of the blue 1 server in our rotation of 3 servers on the load balancer
exhibited message below. A number of users accessing on this server
generated the following error message. I can't see anything wrong with the
'error.vm' -- and it is unchanged since May 2018 and same on the other 2
active servers.
