The output is just the standard error messages of a failed write. It seems
that the socket is closed unexpectedly. I get this error from time to time,
but mostly with a single newline ("can not write to socket: (5 "\n")"). So
it's likely that spiffy tries to write one byte too much. Is it possible that
the client communicating with spiffy in this case closes the connection
too early? The server should handle this problem more gracefully, though.
I will try to address this.

I have not experienced any lockups with spiffy. The only other problem
I found is with broken clients: for example wget sends a keep-alive header,
even if retrieving a single file. Since spiffy doesn't handle timeout, the
connection stays open until the client is forced to quit.
