I wonder how do I eliminate this bug:

[ERROR]] Couldn't write to #<SB-SYS:FD-STREAM

                                                  for "socket 127.0.0.1:3001, peer: 127.0.0.1:45338"
                                                  {100941D0A3}>:
                                Broken pipe


It's hard to reproduce it happens on my server ones in a while.
Is it something fixable? I saw this bug mentioned a long time ago.
I am using the latest SBCL for linux.

Thanks,
