The "connection refused" error could be coming from your server process
when it isn't quite yet crashed but is heading in that direction. The
default listen backlog on a TCP connection is 5, so if your FCGI server is
off the tracks and isn't performing accept() calls, then Yaws could get
ECONNREFUSED when attempting to connect to the server. One way to test this
would be to raise the listen backlog on your FCGI server to see if the
"connection refused" errors go away.

One interesting question here is why the DokuWiki /tmp session files are
causing permissions errors. Are there multiple instances of DokuWiki
running that are somehow stomping on each other, or are there leftover
session files in /tmp from some other instance? Are permissions on /tmp
correct?
